The one about the other guy having a 250th birthday year

As with so many blog posts in the past, I'm here again due to the wonderful world of Facebook discussion threads. In this case, a pianist friend and her conductor/oboist husband were wondering about examples of music in 5/4 time that pre-date the second movement of Tchaikovsky's Symphony No. 6. As it happened, I had been dabbling in this trivia a few weeks before - specifically on "May the Fourth Be With You Day" when another Facebook friend posted this (which actually refers to a Paul Desmond tune made famous by Brubeck);


I fairly quickly responded with a couple of improvised responses to that from Holst and Tchaikovsky:



So, my knowledge of famous 5/4 music also basically went back to Tchaikovsky, but I did sent along a link to this very useful Wikipedia page on quintuple meter which I had run across while investigating May 4. My friends wrote a bit later to make note of an unusual fugue in 5/8 they'd found there written by Anton Reicha. Did I have a clear sense of who Anton Reicha was at this point? (This was five days ago.) Not really. I think I remembered him as someone who'd written wind quintets (true!), though I wouldn't have wanted to be held to that. Contemporary of Beethoven? I feel like maybe I would have guessed that as well, but wouldn't have been surprised if I'd been off a hundred years either way.

My friends also sent along the only YouTube link they could find of the Reicha fugue, and though it seems to be a generic synth rendition (with a mystifying picture of a bunnies for the video), I started listening. At first, in part I'm sure because of the synth sound, it seemed forced and weird, but as I kept listening, I started to get into the swing of it. I listened to it at least two more times on a walk, found a couple of early 19th century editions on IMSLP, and suddenly was in the midst of obsession.

So to back things up, since I shouldn't assume anyone knows much about poor Mr. Reicha, he was indeed an exact contemporary of a VERY famous composer also born in 1770. In fact, Reicha and Beethoven were fellow students and orchestra members in Bonn and later friends in Vienna. Reicha was also a pioneer of the wind quintet and an important teacher of composers such as Liszt, Berlioz, Gounod, and Franck. (Not too shabby). He also wrote a good bit about theory and had some very adventurous ideas about going beyond usual procedures, for example in the writing of fugues. The 5/8 fugue that brought me to this point was published in a set of 36 fugues which push all sorts of futurist boundaries. For whatever reason, though some of his ideas may have been influential (Beethoven became fugue-obsessed in his late years and Liszt was a pioneer in pushing tonality in ways that are suggested in this little fugue), Reicha did not make a big name as a composer, and aside from the wind quintets, he exists pretty much on the music history periphery. (Sadly, his February 250th birthday has already passed, but he still deserves some 2020 attention.)

Although the "ahead of his/her time" metric is not always a sign of greatness, it is remarkable that this 5/8 fugue dates from 1803 (or earlier). I don't know of anything from the period that sounds like it. Curious that the "old-fashioned" genre of fugue should be used for such experimentation.

I'll perhaps write more about it in days ahead, but its quirks include:
  • Being written in the unusual quintuple meter, which Reicha actually indicates as 3/8 + 2/8. 
  • Beginning in A Major but not really being in any particular key. For whatever reason, it ends in F Major. 
  • Having a long, meandering subject which, bizarrely, involves a single triplet and some afterthought sixteenth notes. The triplet is odd in part because the composer makes a point in the preface of being sure the performer doesn't interpret 8ths grouped in three as triplets. And then tosses in a triplet that's not easy to feel in time. But it's also just odd. 
  • Having successive entries of the fugue subject come in at pretty much whatever interval he felt like. The second voice enters a tritone above the first, for example. I guess this is the kind of thing he and Beethoven argued about. (There are eleven entries of the subject, all in major, and they begin on the following pitches: A, E-flat, G, A-flat, F-sharp, A-flat, B, E-flat, C, A-flat, F. Note that the most common is A-flat, and that A never returns!) 
  • Having long passages which modulate freely.
So, yes, it's a quirky fugue, but I have also found it irresistible. Although some of the writing for piano doesn't take best advantage of piano sonority, the notes lie very nicely in the hands, and even though I've now played through it many times, it still feels surprising and even magical. Unlike the inexorable logic one finds in a great Bach fugue, Reicha sometimes seems to be composing on the spot. That nonchalant final cadence in F Major could almost be inspired by someone saying, "Anton, time for dinner!" I still find the meandering tag of the subject (with the triplet and sixteenth notes) to be a little unnatural to the musical discourse, but he just kinda rides with it.

And that's what I'll do here as well, rather than try to analyze every chromatic alteration. Unfortunately, the two early 19th century scores available on IMSLP are both rather poorly engraved, and so I couldn't resist the siren song compelling me to re-engrave the whole thing. I decided to let Reicha keep most of his curious spellings (he likes having one voice in sharps while another is in flats), but there were a lot of spacing issues and also some poor choices about how the voices are arranged across the two staves. He's just one example of a passage that I think is much clearer in my version:


So, although I'm still at the work-in-progress stage, both with the engraving and the performance (on my poor piano which really needs a tuning and re-voicing), I'm releasing this into the wild because I think this is such charming and unusual music. There are at least three commercial recordings of this fugue (here and here and here)*, though they don't seem to be available on Youtube. (Actually I just discovered that the third is available on YouTube Music. It's very fast!) I have listened to all three, and they are fine. But this one says more closely what I think - based on my five days of Reicha expertise!






* Those three linked recordings go from slow to medium (my tempo) to fast. For some reason, on the first album linked, this fugue is listed as #9. I believe all of these pianists play the triplet in the theme a little more slowly then I do, which means I'm probably rushing; but I prefer that sort of headlong falling-forward feeling leading into the 16th notes.

Addendum: A few more observations about my edition and performance. All of the commercially released recordings have the A on the downbeat of m.24 re-articulated, although it is tied from the previous measures in all of the 19th century sources I looked at. This 20th century Barenreiter edition (kind of sketchily uploaded to IMSLP) does not have the tie, and the editor probably had good reason, but I like effect of that tie as it helps this transitional phrase elide more elegantly with what came before.

This brings up a broader point which is that I LOVE that Reicha does not include many articulations or dynamics - in fact, I wish he'd included fewer. I think there's a lot to be said, in music like this, for letting the performer make those decisions. My own set of fugues from the Summer of '18 has no such markings, and though this might be mere laziness on my part, I love the sense of adventure that comes with a good fugue. I play Bach fugues in church many times a month, and I make all sorts of idiosyncratic decisions related to tempo and articulation with them. Many different solutions can be satisfying depending on the context.

Signs and Magic

[If you don't feel like reading a lot, there's a fun new game about 2/3 of the way down. I LOVE burying the lede.]

There's a throwaway line in the article I wrote for the Boston Musical Intelligencer last week which I've found myself thinking about ever since. After boasting that my "blog combines various levels of expertise in writing, rhyming, piano playing, composing, arranging, animating, music engraving, video and graphic design, audio editing, and programming," I felt compelled to add the following parenthetical (bold added for emphasis here):
(I’m a novice programmer but intrigued by the ways in which programming and composition both magically transform bland symbols into entire worlds.)
I didn't want anyone to think I was claiming anything like real expertise as a programmer, which is why I added the first four parenthetical words. The other words just sort of magically followed - which is sort of like how this post has been magically generated by these previous bits of word-generated magic. Sort of.

The two contrasting points I'd want to make about my experiences as a programmer are:
  1. I really am mostly a self-taught novice, with perhaps a creative flair for getting things done, but with all sorts of faults I can't really even articulate - because my faultiness recursively includes not understanding fully what I don't understand - but having to do with writing inefficiently and struggling with more abstract principles of recursion and multi-dimensional thinking. 
  2. I LOVE programming. Maybe in part because I often don't quite know what I'm doing and am not working from familiar internal scripts, it's just always amazing to me when things work. Partly, the speed with which modern processors work and the remarkably flexible, powerful languages available mean that a lot can be accomplished with seemingly little. Paradoxically, there are many things that seems like they should be simple (because our own brains have so many sub-conscious algorithms) which can be a tricky to "explain" to a processor. And confronting that reality, while frustrating, is also fascinating.
The main reason I'm writing about this now is that I've been hard at work on a couple of code-oriented projects the last 2-3 days. One of them is still in process, but it's a music engraving challenge using Lilypond which has required a few deeper-than-normal dives into the program's text-based commands - commands that somehow produce really beautiful-looking music notes.

Unlike a more typical program such as Finale or Sibelius, you generally don't see results in real time in Lilypond. You type out commands and then update the output as needed. Finale and Sibelius will certainly take time to re-format a major layout change, but in Lilypond (using the Frescobaldi environment), even adding an articulation or accidental won't show up immediately in the notation. Although this might sound odd, my favorite part of this process is when I try out some solution, hit the "engrave" button and wait to see what happens. This can take 2-10 seconds depending on the complexity. A lot of times, it's back to the drawing board, but that makes the moments when things work that much more satisfying. 

My other recent project has to do with my day job, which I haven't written about much here. I have mentioned before that this blog got its start when I first started teaching a big arts lecture class to non-music majors. Grappling with "outsiders" who didn't necessarily think like musicians was a big disruption to my own way of thinking, and that's basically why I started blogging. I now teach at a boys prep school, work which includes general music classes for middle schoolers. This has pushed me yet further outside my comfort zone as the need to see things from a different perspective has shifted again. 

Currently, my 7th graders are learning about Beethoven's 5th - a handy topic in this Beethoven year - and I'm always searching for multimodal ways to get the boys into Beethoven's world. (We've done some simple composing using the primary motif, and one mad scientist student put this together in just fifteen minutes of class time after being provided only with the drums and once instance of the motif.) We've conducted the Exposition section of the first movement many times; conducting together is one thing that actually kind of works in this brave new Zoom world. Conducting has the advantage of being physical, without being as intimidating as dance, and it invites a range of ways to feel the music in the body and to pay attention to moments where the pulse is paused and where the character changes. It's also a fun excuse to show videos like this.


Earlier this week, I had each student submit a video of himself conducting the Exposition, and I was impressed by how well they were anticipating what was coming and responding to various style changes. (Was also fun to see the wide variety of conducting styles, from Bernstein-esque melodrama - one even donned a Beethovenesque wig -  to the most serious, sober-minded, technical focus.) So I thought it would be fun to put together a little puzzle game which would require re-assembling musical segments that are out of order. I'm sure that to some degree, something like this Google Doodle from Beethoven's 245th was in the back of my mind, though I wasn't thinking consciously about it.

Anyway, I dove into Scratch, MIT's amazing programming environment for "children" (which I've written about many times before) and after a few hours, I'd roughed out a little game. After a trial version with one class, I put some hours into refining it and adding fun graphics, and here you go:




I think it's pretty cool. It was a challenge for many students, though I had one solve it in less than three minutes. However, after their first attempt, for which they had no previous information about how the music was divided, we talked about what to listen for in each segment - not only what to recognize, but how to think about where it fits into the 8-part structure. (We had already spent a good bit of time learning to identify various themes, using my Beethoven listening map.) I think it was a very successful exercise.

If you don't feel like playing right now, you can watch this demo of the game in action.


Returning now to my parenthetical comment with which I began:
I’m a novice programmer but intrigued by the ways in which programming and composition both magically transform bland symbols into entire worlds.
I'm not saying that musical composition and programming are the same thing, although it is well-known now that computers can compose. My point is that the satisfactions both offer me feel similar. Of course, the situation is muddied by the fact that I do most of my composing and arranging on a computer, and most of my programming involves producing or manipulating music. (Here's a rare game I created which has nothing to do with music.)

But both do feel like a kind of magic. I'm proud to say I built my little Beethoven game in Scratch from scratch - meaning it's not based on another Scratch project. (One of the cool teaching features of Scratch is that anyone can look inside any other published project and copy the code to build something new. Programmers beware - the "code" inside my projects is typically sloppy, uncommented, and certainly inefficient). But even though I basically understand the logic of what's going on, it's still a little miracle when things work.

Here's a little summary of what it's like to do something like this: I conceived the basics of what I wanted the game to do, then put together a series of commands to get it to do what I wanted. This included such basic tasks as creating a function that puts 8 numbers in order by comparing them a pair a time. (A more advanced programming language would have this sort functionality built in, but part of the point of Scratch is to learn this kind of process.) There were multiple ways in which I could've written the instructions, but what matters most is the output. Also, as I worked and confronted challenges and successes, I added many elements to my original concept.

All of the above is pretty similar to what one does when composing, with music notation instead of code. (Yes, it is possible to compose without using notation.) It's also similar in some ways to writing (which also uses "codes") and other creative pursuits, but composition and programming feel a bit more closely connected to me. I find for example that when composing/arranging or programming, once my mind is switched into that mode, it's very difficult to come down from it. (I told my wife that, like drinking coffee, I should really try to stop programming by 6pm or I'll find it impossible to go to sleep.)

As I admitted parenthetically above, my code can be overlong and inefficient, and this is also true of my writing, so in final summary: GO PLAY.

Skip to my loop

This post might create a sort of strange loop for anyone visiting via the Boston Musical Intelligencer, which was kind enough to run an article of mine promoting this very blog. Read the article there, come here, follow the links back there, etc. Anyway, thanks to the Intelligencer for giving me this platform.

I've admired this site since it debuted more than a decade ago, inspired by the legendary Dwight's Journal of Music, a 19th century Boston institution. In a time when major newspapers are not really able (for mostly good reasons) to cover a town's musical scene, the Intelligencer provides a remarkable number of reviews (mostly written by volunteers, I believe) of local events as well as an indispensable concert listings page, various feature stories, and a lively reader commentariat. One can find a wide variety of viewpoints which provide a fascinating and reasonably broad picture of our local musical life. Some of the reviews display high levels of expertise and allow more room for digressions and personal commentary than a newspaper would. The commenter perspective can seem analogous at times to how sports radio gives voice to more than just the newspaper columnists. Although ill-mannered banter sometimes is a result, in general the Symphony Hall gang has a lot to offer, especially in showing how passionately people care about the music that comes to life on our stages.

I've always had an interesting relationship to music reviewers in that 1) I love reading reviews of concerts and recordings, 2) I don't feel like I would ever want to write such reviews. This is somewhat paradoxical because I do enjoy encountering strong opinions, and I sometimes have strong opinions; but I tend to feel like my own opinions about a given performance are too hopelessly subjective to be given the weight of print, virtual or otherwise.

There's also the fact that I don't actually get out to that many live concerts for various life reasons. As I wrote back in 2008, I sometimes feel like Tom Townsend from Whit Stillman's Metropolitan, who would argue passionately about the strengths and weaknesses of Jane Austen novels, only to admit that he'd never actually read the books - just the literary criticism. It's probably fair to say that I enjoy living on the periphery of the music world, diving in every now and then but often viewing from a distance, and the work I do on this blog has a similar relationship to actual performing. What I'm doing here is often articulating around the edges of what's going on in performance of a given musical work, rather than just performing the music and letting it speak for itself.

Anyway, as the Intelligencer concert listings page is a bit more dispensable during the pandemic, I figured this was a good time to promote access to the mostly online musical diversions I've been creating here. It does perhaps feel a little dissonant to promote my own "play" in a time of suffering and loss, but of course all artists are grappling with what it means to make art in such times. And I do intentionally use the word "play" to suggest something more substantive than it might first appear. I have definitely found that I'm listening to music and thinking about music more during the past two months, and though there may be some element of escapism there, it's also about connecting more deeply with music's expressive and spiritual power.

As for promoting the blog, I am always hopeful that my strange creations will find their audience, however spread out around the world that audience might be. And I've also always wanted to resist the idea that a blog is just an ephemeral collection of passing thoughts. Packaging a lot of those thoughts together is a way to affirm that something more lasting is happening here. As I wrote way back in 2008 when I debuted my "Multimedia Musing Machine":
George Costanza once said, while trying to impress a NYC tour guide who thought he'd just moved in from Arkansas, "You know if you take everything I've ever done in my entire life and condense it down into one day... it looks decent." To paraphrase, "if you take everything I've ever done in my entire blogging career and condense it down into one post...it looks decent."

The 11 Days of Bach: Tweaks and Reflections

It's been a few weeks since I finished up a major Bach blogging project with a down-to-the-wire demo of a new "Chaconne at a glance" page. I've used some vacation time this week to add lots of fun features, and I'm quite pleased with the result, though I'm sure I've missed some bugs. (One thing that is certainly true about any sort of coding project is that every new feature brings with it a seemingly exponential new range of "things that could go wrong.")


The major new features are:
  • Four-bar segments are now auto-highlighted, both as you search through the score and mouse-hover over them and as the music plays. This makes it easier to follow the score. (This may seem and hopefully looks simple, but getting this functionality going took a lot of experimenting and tweaking.)
  • Score navigation has several added features:
    • Arrow keys (on keyboard or on screen) may be used to jump forwards or backwards among the 4-bar segments.
    • The SPACE key may be used to play/pause, and clicking in the score will begin playback from the segment clicked. (Playback can also still be toggled via the Play button or by clicking on the larger 4-bar segment shown at top.)
    • In addition to showing the elapsed time, the counter in the upper left corner now shows which of the 64 segments is being played.
  • Functionality on mobile devices is much improved. I find that I can get around pretty well on my iPhone (though the arrow buttons are hard to hit, and the mouse-over feature doesn't work) and it's really satisfying on an iPad!
  • I've added an old "listening map" of the Chaconne which I made years ago for a class of non-music majors. For now, it just sits below the score, but it is also click-enabled to the recording. 


As it says on the site, this organization of segments is just a subjective suggestion of how one might hear Bach's ideas. The main point is to hear the music as something more than just 64 4-bar sets. At the bottom of the new page are some observations about the overall structure.

This whole project has been both very time-consuming and immensely rewarding. Though I'll never play this music on the violin, I could probably have learned at least the Brahms left-handed version of this piece to a passable degree in the time it took to do all this (we'll leave Busoni out of this). Maybe I should have! But the constant engagement with the music (I can't begin to imagine how many times I've heard this piece start up while testing things out) has been a different sort of playing, and I have something to show for it. Hopefully, someone else will enjoy holding Bach's music in hand this way.

More broadly, my 11-day Bach project itself was a fun dive into the kinds of work I love to do. You'll find there various levels of expertise exhibited in piano playing, music engraving, composition, arranging, audio mixing, programming, and graphic design, although somehow poetry didn't make it into the festival. Maybe next year. I wasn't at all sure what I was doing when I started out on March 21, and that's the most fun thing about blogging. You never know where it will lead. Here's a series review:

Bach Day #11: Chaconne at a glance

[UPDATE (4/23/20): The page debuted below has been updated quite a bit, with many new navigation features. Check it out. The original version of the page referenced below is here.]

Well, it's been an exciting few days here at MMmusing, trying desperately to get this final project finished in time for Bach's "new" birthday. As I understand it, Bach's birthday was properly referred to as March 21 during his lifetime, but some sort of calendar adjustments mean that if we were to count back from now, we'd find he was born on our March 31 in 1685. And that gave me this lovely excuse to indulge in a lot of Bach blogging over these past eleven days during this odd time of quarantine. I won't deny that there's something particularly satisfying about spending time grounded in this music during times of uncertainty. (Of course, all times are uncertain.)

The project I'd most hoped to get off the ground has been bugging me since about three years ago, on Bach's old birthday, when I debuted a one-page version of the great Chaconne in D Minor. I've always found it appealing to be able to look at something monumental like this in one glance. Here's an absurdly bird's-eye view:


Absurd and wonderful. Such shape and character.

But since then, I've wanted to build a page around this image that would do something. Alas, all I have to offer is a prototype for now, but I'm pleased with where this stands since I basically had nothing as of yesterday.* I was able to build off the structure of my Musical Manipulatives (still kind of prototype stages as well), so I didn't have to reinvent the JavaScript wheel, which is good because my knowledge of JavaScript is pretty half-baked. I could tell many stories of the heartaches I experienced just in the last 24 hours getting this far, but somehow I have a workable thing. 

I don't know that it will be of much use on cellphones, and I certainly haven't yet been able to cross-test it across browsers, but on Windows Chrome, it does pretty much what I want for now. When you go to the page, you'll find a simple design (needs a little tweaking) with a play button in the upper right. Start it going and you'll see somewhat larger versions of the music in the upper frame. (Timings could also use tweaking - this was just a one-pass attempt to approximate.) Click on part of the music below and, hopefully, the outstanding performance by Ray Chen will magically jump to the correct part. That's pretty much it for now, but being able to "hold this music in virtual hands" this way is really fun.

The Lilypond-generated score(s) could use a lot of tweaking as well. Because Bach often writes up to four voices on one staff, decisions about how to show that are very tricky, and I've mostly just gone with defaults for now. So, I've got much work ahead.

But why spend more words on this now when the picture on the page linked below is worth so many more words?


Happy Birthday, Bach!

* 6 hours ago, I was pretty sure this blog post title would be "Bach Day #11: IOU," as there were some technical hurdles I didn't think I'd surmount. Also, 30 minutes ago, I was pretty sure this blog post title would be "Chaconne à Son Goût," until a quick Google search told me another Bach had made the same joke before.

Bach Day #10: Giving Up?

Well, I'll admit this Day #10 of "The Eleven Days of Bach" has left me a little empty-handed in terms of new material. I thought and thought about what I should feature from the past - not Bach's past so much as MY past. And I finally decided I might as well follow my heart. Here's something I wrote in a blog post about six years ago.
....although I'm still not sure what my place in the musical universe should be, I feel pretty sure that I'm the only person in the world who would have made THIS video:



So, if I didn't post this today, who would? I'm still rather proud of this elaborate viola joke which involved me re-writing a Bach prelude to incorporate "Pop, goes the weasel," playing it as badly as I could at half-tempo on the cello, and then doubling the speed to make it sound like...well, a viola.

You're welcome. I'll try to redeem myself tomorrow.

Bach Day #9: My Jesus, Joy of Man's Desiring

I'm keeping things simple on this Second Sunday of "The Eleven Days of Bach," and to be honest, after managing to get the new version of Bach's Canon per tonos up and running and fixed, etc., I'll probably keep it simpler for these last three days. I had one other major project mentally in the works, but I think I'll need more space and time to get that finished.

Having focused the last two days on one of Bach's more forbidding compositions, today features what is surely one of his most accessible and beloved tunes, the ever-popular Jesu, Joy of Man's Desiring - but with a twist. The funny thing about that work, which is originally from the Cantata 147, is that though it is a setting of a chorale melody (basically a hymn tune), the tune itself is quite simple and not that interesting. The "melody" everyone knows is the running triplet accompaniment which Bach wrote to adorn the chorale. Though it is too busy and fast-moving to be very singable, it combines pattern and variety in a way that is memorable and has become iconic.

Back in 2011, I debuted a two-piano arrangement of another simple hymn tune, A. J. Gordon's "My Jesus, I love thee," which uses Bach's "melody" as accompaniment, but with additions made to move from a 3/4 to a 4/4 context. You can read more about this arrangement here, featuring an impromptu home recording with my young violinist daughter. A couple of years later, she and I performed it in recital in a new version adding my wife on cello:


Although it is obviously a distortion of Bach's original, I think the "idea" of the Bach is maintained and it was interesting to experiment with the malleability of the original material. The moment I'm most pleased with is at 3:08 in the video above when, over the familiar pedal tone, the third phrase of the hymn tune is stretched out in running 8th notes across the triplets.

That's it for today. No 30-minute videos, no pitch-bending distortions. Just a little Bach twisted into something new.

Bach Day #8: Listening to Math

Today I spent a fair amount of time fixing a couple of mistakes that had been hidden (from me) in yesterday's 30-minute version of Bach's Canon per tonos from The Musical Offering. I noticed one mistake while listening to the WHOLE thing cooking breakfast, and a friend with a very good ear noticed the other. It's rather crazy that I tried to get that complicated project online so quickly, but it's the way I tend to work; if I didn't do it this way - I probably wouldn't do it. I'm sure other little things could use fixing as well, but hopefully nothing major. So, first of all, here again is the latest "corrected" version:


The main thing I wanted to add today is that, as much as I admire Bach's craftsmanship, I can't really say I think this is a great piece, which is one reason it has surprised me that my earlier version has been so popular on YouTube. And I doubt Bach would argue. It's more puzzle than art perhaps - not that the worlds are mutually exclusive.

Just look at how simple the original is on the page:


That's all there is to it, though the second canonic voice is not written out, nor are the modulations. Bach wants the user to figure out how the music goes. But as music, it's rather perplexing. Of course, it doesn't help that the whiny theme Frederick the Great presented to Bach is so unwieldy. The music of this canon is overindulgently chromatic, the cadence into the repetition is hardly satisfying (which means it never really feels resolved), the rhythm is odd, with lots of offbeat notes that sound less like syncopation and more like general disorientation, and the general tone is one of restless busyness.

I've always found it comical that Bach appended the following to this puzzle: "As the modulation rises, so may the King's glory rise." OK, but it does not sound very glorious. The fact that the top voice is mostly descending doesn't help. (As with the Shepard Tone principle, the descending melody helps camouflage the tonal motion upward.) Of course, paying tribute to the King's theme is a way of glorifying him, I suppose, and it's Frederick's own fault that the tone is so somber. (To be fair, the clumsiness of the theme was perhaps part of the challenge in the first place.)

But I DO like this canon! I like a lot of things that are odd, and the fact that this sounds kind of like someone working out a math problem isn't so bad. (I also like math.) One can hear a kinship with some of the harshly intellectual music of the 20th century from the likes of Babbitt and Boulez, music that is uncompromising in its commitment to its own logic. When I listened to the whole 30-minute version this morning, I found it soothing and stimulating, an interesting combination. Eventually, that sense of never arriving becomes its own strange comfort.

Unfortunately, I did have one more thought - which I only later realized I'd seen executed elsewhere. It occurred to me that another "solution" to the ever-rising problem is to slide downwards continuously over each 8-bar group. By sliding down a whole step over this time, we end up magically where we started. Since Bach called his piece a "Canon per tonos" ('tonos' referring to movement by a whole tone), I'm calling this "Canon per microtonos." I did NOT spend a lot of time on it, but imagine an instrument in such bad shape that the strings are constantly loosening. Wait, you don't have to imagine!



I'll admit that I had a vague sense of déjà vu that I'd thought or heard of this concept before. I finally did a search and remembered that the remarkable Stephen Malinowski had done much the same thing, though using synth strings, with his Musical Animation Machine. That version is arguably more successful at disguising the pitch drop, though I like the clattering harpsichord - and everyone's already used to harpsichords being out of tune!

Maybe you'll need something to cleanse the ear after that, so here's one last possibility. Just let the music rise until it disappears. It turns out that using the basic synth built into Finale, it can go pretty far up using the piano sound, and it becomes quite charming and ethereal. (WARNING: I also found my head hurt a bit after listening to this...]

Bach Day #7: Bring out the Canons!

So I've been blogging and posting multimedia for more than thirteen years, and honestly there were a few times that I thought I would hit the big time. Not yet! However, my two steadiest performers over the years (the "big guns," one might say) have been two relatively simple animations I created of canons from Bach's The Musical Offering, so I knew they'd figure into these eleven days of Bach.

In fact, of the almost 900,000 YouTube views I have as of today, more than a third of them are for a video of the endlessly rising canon, the "Canon per tonos." (The title "per tonos" refers to the fact that this canon rises by a whole tone each time through.) To my great surprise, this video has amassed more than 340,000 views. My version of the crab canon has just over 200,000 views, so together, that's well over half of my YouTube audience.

Both videos are, from my point-of-view, more notable for audio tricks I played than for the animations, adorable crabs aside. For the crab canon, a single melody played against itself backwards, I actually recorded the melody only once and then reversed the audio to create the second voice. A YouTube commenter alerted me not too long after I'd posted it in 2008 that it had a wrong note in the score and recording. Ugh. Fortunately, that only took me a little over ten years to fix. That wrong note has been seen and heard many times!

As for the endlessly rising canon, I used a technique suggested by the great Douglas Hofstadter in Gödel, Escher, Bach. Because the basic structure is that the 8-bar canon modulates up a whole step each time through, a performance taken to its logical conclusion would actually run out of playable/audible pitches. Hofstadter's idea was to use the Shepard Tone technique by which the constant, gradual introduction of a lower octave occurs while the original octave fades out above. If executed correctly, the listener doesn't really notice the switch, but finds that the music, having risen an octave, is right back where it started. Here's a version of a Shepard Tone illusion created by a Wikipedia contributor:



Notice that the tones seem to be descending continuously, but they never run out of space. The effect is often compared to a barber's shop pole. Of course, applying this effect to a musical composition is something quite different.

My first attempt "to Shepard" Bach was posted more than twelve years ago, and though I'm pleased with it, I've always intended to fix some things. Among the problems with the original are a few misspelled enharmonics, the stubborn refusal to change clefs (resulting in some wacky ledger lines, although it makes the overall "rising" effect clear), and most importantly, the failure to go beyond two full times through the sequence. In the decade that has passed, there are far more novelty YouTube videos that go on for hours, and this was an obvious candidate for that approach (though I stopped at half an hour).

So, the truth is I had all these thoughts three or four days ago and figured it wouldn't take long to make a new version. As with so many projects, I mapped it out in my head and thought, "just do this, this, and this" and I'll be good to go. But I've realized that, though it's a straightforward project in many respects, the details, details, details kept multiplying. I also had to make choices about how much I wanted to copy things I'd done in the first video and where I wanted to do something different.

The two biggests tasks were recreating the score (in my beloved Lilypond) and making a new recording. I actually thought about sticking with the original acoustic guitar version, as it has a nice mellow quality that's suitable for endless listening. But I thought it would be more fun to try something new, since that video is still available. After a lot of experimenting, I felt the virtual harpsichord provided the most authentic and satisfying effect, though the sound is perhaps a little more annoying. I mean, it's a harpsichord sound. (I'll leave the Beecham jokes out of this.)

Creating the cross-fade effect is trickier than it sounds, and after much tinkering, I was also reminded how different the results can sound depending on the dynamic range of the speakers being used. But I think I've settled on something that basically does the job. It really does keep rising without going anywhere, though it's not so hard to hear why that's happening.

As for the score, I struggled over many decisions. Unlike the previous version, I finally decided NOT to use key signatures. Bach's version only shows 8 bars, which clearly start in C Minor, but with no signature. He doesn't even include the middle voice! The performers are supposed to add in the canonic voice, which follows the lower voice by one bar and a fifth above, and then work out the transpotions for each repetition.


Although key signatures are a nice way to signal change of tonality, the music is so chromatic that it actually reads a little more smoothly without key signatures since so many notes end up changed anyway, especially as the modulation is prepared for the next key. Also, after flirting with the elegance of alto clef, which mostly works beautifully for the middle voice, I finally decided to stay with treble and bass clefs only, with discreet changes along the way, simply because more people read each fluently. I did keep a couple of quirky features from before: the barlines do not connect the staves (it just looks cleaner this way) and I kept the little cue note at the end to show the new tonic that is coming.

Well, that's surely more than anyone wants to know about the endless hours I put in this week creating this endless video, so perhaps I should just finish with the video. Tomorrow, I'll write a bit more about the work itself. If the last two days focused on Bach at his most jovial, this is surely Bach at his most austere and cerebral. And, spoiler alert: Frederick the Great's theme (on which all of The Musical Offering is based) is....not that great. But we know Bach liked a challenge....



UPDATE: The morning after posting this I listened to the whole thing while making a big breakfast - and discovered a mistake (a volume irregularity in the middle) ! It has now been fixed.

UPDATE #2: There was another mistake, but thanks to the great ears of a great friend, it has been fixed as well, along with a few other minor stylistic tweaks. Putting something this complicated out so quickly is kind of insane, but it's how I roll.

Bach Day #6: Pass the Popcorn

To continue with some of the levity from Day #5 (there is more "serious" Bach ahead), I'll just do a quick re-share today. I mentioned the C-sharp Major fugue from Book II of The Well-tempered Clavier yesterday. It's a piece I "discovered" a few years back when I was looking for a church postlude in D-flat Major, and I turned from the Book I fugue I'd known well to this delightfully compact, intricate romp, which is full of surprises.

When I wrote about it several years back, I quoted my blogger pianist friend Erica Sipes' vivid description: "The fugue reminds me of popcorn popping...starting with a kernel or two as the oil heats up and then speeding up as they all start popping." This image ended up playing a big role in one of my most elaborate Scratch projects, a little program that plays and plays with this fugue. You can change the tempo, change "instrument," put in temporary ritards and accelarandi, invert the whole thing, make it play with all three voices in different keys, play microtonally, etc.

The whole time it plays, popcorn kernels are randomly popping, which is a nice analogue for how little outbursts of fast notes pop up all over the score. And speaking of the score, you can switch back and forth between score view and popcorn view and, yes, when the music inverts, the score inverts as well. Honestly, I'd forgotten how much this silly little program does, which is a nice analogue for how much Bach does in this silly little fugue.

Here's a straightforward "performance" of the fugue by my program:



...and you can go to this fancy page in which the program is embedded with lots of instructions to let you create mayhem.


P.S. Bach's wig in the Scratch program is one of my better creations, by the way.

Bach Day #5: LOL

A couple of my Bach projects are dragging along more slowly than expected - music is hard! - so I'm going to lighten my own spirits on Day #5 of 11 with the silliest, most humorous music by Bach that I know. Yes, he wrote plenty of jaunty gigues and other dances which have lighthearted qualities, and his counterpoint can be effervescent. For some reason, for example, he seemed amused by C-sharp Major and wrote two of his giddiest fugues in that key:



[By the way, though I like Glenn Gould's approach to the Book I fugue, he plays the Book II fugue at a slower tempo than I could've imagined. It's SO slow, it's still kinda funny.]

Anyway, this is a lighthearted post about some music by Bach that is not just light or fun. No, this duet from the Cantata No. 78 "Jesu, der du meine Seele" is really laugh-out-loud silly, especially in this fantastic recording by the American Bach Soloists.



The text in English is as follows (translation by Pamela Dellal from the amazing Emmanuel Music archive):
We hasten with weak, yet eager steps,
O Jesus, O Master, to You for help.
You faithfully seek the ill and erring.
Ah, hear, how we lift up our voices to beg for help!
Let Your gracious countenance be joyful to us!
The way the two soloists chase each other around is clearly a whimsical take on the idea of following weakly in Jesus's steps. Perhaps not every recording/performance is quite on the same Goofy Greats level as the one above (and I mean that with all respect and admiration - just listen to their way with "zu dir"), but I do find the tone and bounciness of this music to be an outlier for Bach. That's not necessarily a bad thing, because I love his more typical fare, but it's nice to hear him letting his powdered wig down a bit.

The combination of that non-stop bouncing bass line and those twirling vocal lines makes the music seem a bit simpler and sunnier than so much Bach, even though there is still lots of cleverness in the construction.


I suppose maybe there's a certain kinship with the wonderful Brandenburg Concerto No. 6 (Desert Island material for sure) with its follow-the-leader soloists and simple bass line [listen starting at 48.12 here].



But as joyful and cheerful as that music is, it's just a little too dignified to be ridiculous. I'm glad Bach left behind at least one bit of music that cheerfully crosses that line!

Bach Day #4: Orpheus in the Underworld?

Well, life definitely caught up with me today, and although I did get some work done on something new, it's not quite ready yet.

So, we return to the winter of 2009 and a Bach recording I've always been pleased with. As described in this post, the recording was made pretty informally, with a few tidying-up edits made later. It was originally posted without score, which I added in 2011. The video only shows the orchestral score, from which I more or less made up a version (it helps that the keyboard part covers much of the material). Someday I should create an honest-to-goodness notated piano version, but that will have to wait.


The music is better-known as the slow movement of the composer's Violin Concerto in A Minor, but there is a harpsichord version of this concerto in G Minor. As so often happens with Bach, music that seems perfect on one instrument can turn out to be pretty satisfying on another as well. Here's what I wrote about this back in Aught Nine:
I hear the slow movement of this concerto as a sort of "Orpheus Taming the Furies" dialogue. True, the orchestra isn't as gruff as in the famous "Orpheus" movement of Beethoven's 4th piano concerto, but there's a stubbornness in Bach's bass ritornello that the solo passages seem intent on melting. The final solo statement is a miracle of sweetness and simplicity, so perfect that there is no concluding ritornello. It's less a victory than it is a unification of opposing forces. Honestly, I can't really put into words what happens in this musical dialogue, so I figured I'd just play it.
There are many compromises at play here. First of all, all those long, suspended notes the violin sings can really only be imagined as sustaining that way in a piano version. Second of all, I didn't have an orchestra available when I slipped into the recital hall early this morning, so it's just a dialogue between my two hands, not a violin (or piano) vs. orchestra. I did my best to incorporate the orchestral violin parts, but I'm inconsistent about that. Third, I only had about 15 minutes, so I just sat and played, and when I had a couple of slips, I backtracked a little and then stitched things together later this afternoon. It's far from perfect. But, whatever. I really love the way it sounds this way, and in some respects the fragility of the piano sonority just adds to the impossibly beautiful writing.
In 2011, when I added the video, I also added this comment:
I remember that when I first heard this music years ago, I found the repetitiveness of the bass line to be a bit annoying; but perhaps it's supposed to be that way, and I think it's quite telling that the R.H. melody gets the last word.
I've also always been puzzled by that rhythm in the bass - the stubborn "Furies" rhythm. Although I believe it should basically be played as written, the fast notes always somehow feel more like triplets. I think I'd thought that's what they were from a recording I'd heard before I ever saw the score.


I can't really put my finger on what I mean exactly. I actually tried having a synth record this with a rhythm halfway between the "16th + 2 32nds" and a triplet, and I also tried just adding a tiny bit extra to the triplet (so that each measure ends up being a tiny bit longer), but I couldn't generate what I was hearing. So you're just stuck with my performance! Perhaps after three days of me bragging about robo-performances, it was about time the computers lost one.

Bach Day #3: Bach to Bach

I promise not every day of this 11-day Bach-a-thon will be about the Preludio from the E Major Violin Partita, but we'll take one more "trip" in that direction today, and then head down another little stream tomorrow. (Bach, of course, is German for brook.)

Before getting to today's admittedly silly bit of play, I thought I'd reflect a bit on some bigger picture questions about WHAT WE ARE DOING. I think about this probably way too much, the written and unwritten rules that govern how we think about classical music, and the ways in which I love and fight against those rules. "Playing Bach" does not normally mean treating the great master's exquisitely crafted compositions as so much silly putty for one's own repurposing pleasure. Rather, "playing Bach" generally means trying to recreate as closely as possible the musical ideas Bach had in mind. And I do still find satisfaction in that. 

But I also find a lot of satisfaction from recomposing and distorting what's on the page. Of course, it's worth remembering here that Bach himself spent a lot of time reworking compositions by the likes of Vivaldi and Marcello (Alessandro & Benedetto!), and though my post-modern reworkings may seem to be in a different spirit, they are grounded in the joy of conversing with the past. Bach's music is conversational in so many ways. (It's also often improvisational, which naturally invites conversational feedback.) Counterpoint, his great specialty, is itself a kind of conversation, but there's also something conversational about the way his melodies unfold. I almost literally hear them talking to me and saying, "what's your response?" (Ok, that's not really true, but it sounds cool.)

There's also something usefully strong and resilient about music that is well-known and strictly patterned, because experiments with such music can use this familiarity and structure as a center of gravity. Although I'm not such a big fan of wildly dissonant music in general, I really enjoy bouncing dissonance and complex rhythmic tricks off of music that our ears can hold on to, as explored in the annotated video I posted yesterday. (As I've discussed before, Timo Andres' Mozart concerto distortion is a great example of this kind of thing.)

Here's something I wrote back in 2011:
...though I am clearly sympathetic to postmodern deconstructions of how we hear and experience the world (e.g. Bach's music sounds greater and more meaningful to us than it otherwise might because of cultural conditioning), I'm surprised at how often postmodernists just leave these deconstructed messes behind as if there's something wrong with loving something for culturally embedded reasons. I think this lies at the heart of what it is to love classical music (or just about anything we love via culture) - this big sense of connected-ness, the way in which one musical work calls out to another, the way in which we listen within these wildly divergent but related frameworks.
I think my point is: 1) I'm happy that there are so many scrupulously faithful recordings and performances of Bach's music in the world, even if their existence flows in part from some arbitrary ideas about what being a musician should be; and I'm happy in part because 2) the existence of that enormous galaxy of all things Bach provides a stimulating jumping-off point for all sorts of post-Bach things.

And that could be a book. But for today, here's my latest attack on the Kapellmeister. 

Having created an independent left hand to go with Bach's solo violin line, I couldn't help but think about pitting Bach against himself. Fortunately, the wonderfully magical Lilypond makes it easy to invert, reverse, and otherwise manipulate musical ideas, so it didn't take so long to create this two-part invention:



There were a lot of choices to make, the most important of which was to create a counterpoint that is a completely exact inversion of the original. This means that harmonically things go to pieces almost right away, and in fact, I did experiment with tweaking the inversion to make more sense, but....that was gonna take a LOT of work, and I wasn't sure it was worth it. I love the zany interplay that happens here.

I won't go into all the technical stuff, although I was surprised to realize how well it worked to put the lower part in C Major. (Technically, it's E Phrygian, a notoriously intense mode, which explains a lot about the results here, but the key signature is the same as C major!) Inverting the steps of a scale in E Major results in the following natural set: E F G A B C D E. Once I realized that, I knew I had to stick with this pure inversion rather than some wimpy modal alterations. Notice there is not a single accidental in the lower part until the first accidental shows up in the original in m. 19. The spelling choices are odd in many places (check out the E-sharp vs. E-flat in m.34 and following!) and not what would be done in a proper score - but they nicely represent the inversion principle. As with my arrangement posted on Sunday, this is not really music made for human hands.

I also gave up and put some long stretches in alto clef (!) because some of the more expansive passages simply wouldn't sit well in treble or bass, and the purist in me wouldn't let any of the mayhem be tempered by register shifts. Because I chose the inversion split-point to be the E above Middle C, this also means there's a significant amount of "hand" crossing. For better or for worse, this is what was meant to be.

There are some delicious dissonances in places like mm. 32-33, and and maybe my favorite moment is m.78 in which the crossing parts end up just trading notes completely - so it just sounds like one buzzing minor 7th for a whole bar. I have some small regret the climactic cadential chords in m. 134 are a complete disaster, but there was no turning back at that point.

So that's that, although I should mention some previous MMmusing two-part experiments that are echoed here:

  • Bach Doubled - a Courante and its Double combined.
  • Re-Inventing Bach - inverting, retrograding, and retrograde-inverting a famous Bach invention.

Note sure what's coming up tomorrow, but I will leave this poor Preludio behind...

Bach Day #2: Left-handed Complement

So I've made it to Day 2 of my 2020 Bach-a-thon, just under the wire again.

Today's subject is: ME! Or rather, to discuss a bit more what it is I've done to Bach in the video I posted yesterday. To review quickly, this arrangement (minus a few 2020 tweaks) was originally made last March, inspired by a differently mischievous left hand part added by composer David Bruce. Bruce's basic goal was to bring out some of the inherent metrical ambiguities hidden in Bach's original work for solo violin. [Again, here is a really fun playlist, beginning with Bach's original, and continuing through many varied re-interpretations.]

The original Bach is composed almost entirely of running 16th notes in 3/4 time, but there are several passages in which the note groupings can be interpreted as something other than steady groups of 4 (which is the main topic that drew Bruce to his project). I know this well, because I've heard this piece hundreds and hundreds of times (my two daughters have each learned it), and I regularly experience cognitive/metrical dissonance because I lose track of the downbeat.

Here's an example of a passage in which my ear/brain almost always shifts the barline over by one 16th. Starting around m. 20, as the lowest note in each group of four gets lower and thus stands out from the three preceding, it just starts to feel like a downbeat. I've tried to illustrate what happens with this little video. It first shows (with aggressively accented beats) where the groupings actually fall. The second version shows one of the places where my ear will experience a shift and start hearing the downbeat one 16th note early. What's interesting is that I rarely experience this as if I've been cheated. It's only when the end of the passage comes, going into m.29 that I'm aware of an extra 16th note - almost like a record skipping. That's a lot of words, but maybe this makes sense:


David Bruce claims that most of his compositional choices are based on possible implied groupings in Bach's original. When listening to his version, I found myself skeptical in many places - but I also liked the places where the Bach seemed to be twisted beyond its own internal logic! So, the point of my own project was to be continuously disruptive, with all sorts of metrical tricks along the way. There are triplets that start on off-beats, downbeats shifted into odd places, rhythmic groupings of 3, 4, 7  16ths notes, etc. The process was honestly rather casual and improvisational ("hmm, let's try this") and took a LOT less time than it has for me to engrave the results. Rather than try to write about all of the choices, I made an annotated version that over-explains much of what is going on here:


There's a lot more that can be said about all of this, but I've got nine more days of Bach blogging to go. I will say for now that my "arrangement" is not necessarily intended to be performed by a human pianist, though I don't doubt there are those who could manage just about all of this. I might try to learn it at some point (I've managed the first 30 bars or so before), but part of what I love best about this is the absolute steadiness of Bach's right hand as essayed by my computer. When I listen, it's especially fun to try to keep the original 3/4 meter in mind - kind of like trying to organize an image fractured by a trick mirror.

Also worth noting that one of the most enjoyable things about this project is getting the notes to look right on the page (including for the "rhythmic feeling" demo above). There are choices I've made that would make this harder for a pianist to read - but that make it easier to see what's going on. That's an interesting tension in itself. More tomorrow...

I'll be Bach

Well, this day has almost completely gotten away from me, so the bigger post I'd had planned for Bach's birthday will have to wait. But, good news. Whereas I've spent most of my life thinking of March 21 as Bach's birthday, I guess there is also reason to celebrate on March 31. I mentioned this on Facebook, and a friend said he and his family had taken to celebrating eleven days of Bach, from the 21st to the 31st. Brilliant!

So, I'm gonna try to Bach-blog every day to the end of the month (giving me a flimsy excuse for my post title), beginning today with a new little reveal.

This "adaptation" of a famous Bach work actually debuted last March with not so much fanfare. In short (with more explanation to follow tomorrow?), I simply added an intentionally disruptive left hand part to a solo line originally written for one violin. I really liked the way it came out, and have listened to it happily many times, but had posted a version that only shows the original violin part. Because my left handed addition plays lots of metrical tricks, it's not so easy to notate, and it was only on March 1 of this year that I set out to make it look right. There were lots of interesting and unusual decisions I made along the way, and what you see below combines my interests in arranging, deranging, engraving, and score animating.


As I'll discuss more, it's not necessarily intended to be performed by a person which is one of its disruptive features. But it makes my brain dance in satisfying ways, and though it is not pure Bach, it definitely flows from a love for what his music does to my mind. Happy Birthday, Bach!

===========

J.S.P.S. Might as well include this as well:

Oh, and a playlist that shows the many, many ways this music has been re-imagined.

Notes that float

As the Internet, social media, and blogs have evolved over the years, it's likely that more people now see this blog (if they see it at all) on a mobile device than in its true webpage form. This is a little sad for me since I once spent a lot of time tweaking the Blogger templates to create a look I really liked. A typical mobile trip to MMmusing won't even show cool things like my should-be-patented "Multimedia Musing Machine," nor will it show my homemade Bachground wallpaper.

I also recently remembered that the web version of the blog has long featured a link to one of my favorite recordings of my own playing. I opened a 2012 recital (wow, so long ago!) with the Allemande from Bach's Partita No. 4 in D Major. I'd fallen in love with this piece after reading Jeremy Denk's wonderful 7-part blog series about it back in Aught-Seven. (Denk's series begins here.) 

I continue to find it unique among Bach's works for its meandering qualities, melodic but not in a particularly memorable way (meaning there's not really a singable tune). Rather, the highly ornamented right hand rolls along with a wide variety of rhythmic figurations and a sense of harmony that seems more free-floating than "typical" Bach. It manages to be improvisatory and intricate. And inspired.There's nothing else quite like it.

I have nothing against the other six movements of this suite, but this Allemande definitely stands on its own. (It is not as out-of-scale as the mighty Chaconne is in the D Minor violin partita, but it is unusually long and winding for an Allemande.) I also have nothing in particular against other recordings of this piece, but my own performance happens to say just what I would want this deeply personal music to say, so I figured it was time I posted it on YouTube. As it is a live performance played in front of an audience from memory, it is certainly not perfect, but it's really not the kind of thing that needs to be perfect.

To accompany the recording, I prepared my own engraving of this ornate score in Lilypond, a rewarding creative challenge in its own right. Because this music has such a linear quality, as if Bach is inventing each new melodic diversion on the spot, I liked the idea of a continuously scrolling visual. Lilypond has a function which makes it easy to create a score that extends horizontally for exactly as long as needed. Imagine a short sheet of paper (only needs to accommodate the height of two staves) which stretches out across the room. 

I also allowed Lilypond to let the music spacing breath a bit more than I did when preparing a companion "normal-sized" copy. When printing to paper, all of the elaborate rhythms (some measures include as many as 24 notes across) have to be made to fit within orderly staff systems and with some degree of logic across multiple pages. For a long scrolling video score, it's actually better if the measures are relatively uniform in length so that the scrolling speed doesn't have to vary too much, whereas normal engraving will usually take more advantage of less dense bars by compressing their spacing.

In some respects this is a work-in-progress, but I was happy to develop some more techniques both working with Lilypond and in creating scrolling animation. I have some other projects up my sleeve that will require more of the latter. 

But for now, I'll end this rather discursive post with this sublimely discursive bit of Bach:


A few postscripts:
  • I am aware that the notes in the video are rather small. This is in part because using bigger notes would mean faster scrolling which can get a little dizzying, but also because I'm more interested in the visual than in the specific details. As I've written many times before, although there are plenty of nice ways to accompany music with visuals, I don't think anything beats the beauty of a musical score. Obviously, it provides a very close analog to the sounds being heard, but I find that listening while watching notes often helps to sharpen the ears. [To be totally honest, I wish the notes were a little bigger, so I might re-do this, but it takes time since quite a few synch points need to be entered manually to make the music flow properly.]
  • Though still a work-in-progress, you can see what my engraving looks like on paper via this download.

Thirteen

Today just happens to mark the 13th anniversary of this blog. (MMmusing is a teenager!) And 13 just happens to be a Fibonacci number! So what better way to mark this occasion (and finish up this little blog series) than with a bit of Fibonacci fun?

In my last two posts, I talked about encounters I had with the Golden Ratio and the Fibonacci Sequence while preparing to lead some musical sessions as part of a broader academic day focused on those topics. I've already written about looking for the Golden Ratio in Beethoven and about writing a little vocal warm-up using Fibonacci numbers.

The latter is based on a simple diatonic pattern in which the primary notes of a scale (the "white notes" in C Major) are used as stepping tones for scalar ascents of 1, 2, 3, 5, and 8. Naturally, I was also interested in exploring larger numbers in the series, and though it's not practical to sing a range covering 55 notes, the piano keyboard can easily accommodate that. EXCEPT, I was actually a little surprised to realize that the 88 notes of a piano include only 52 white notes.

So, although I like the way the diatonic Fibonacci patterns emphasize the 3rd, 5th, and octave of a major scale, I set to work organizing the full chromatic complement of white AND black notes, which easily accommodates the Fibonacci 55. Sadly, the next number in the series is 89, and that's one note too far, but I also feel there might be diminishing returns if the number stretches out too far. (See postscript #1 to test this out.) It becomes difficult beyond 55 (or maybe beyond 21 or 34?) to feel the relationship to the groups preceding.

Anyway, the skeleton of my piece-in-progress is this very simple expression of Fibonacci numbers through expanding meters (Remember, the Fibonacci Sequence begins: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55):



There's not a lot of real "composing" going on there, but I then added a right hand part to emphasize some of those metrical tricks, build suspense, and also help support a vibrant ending in which a big C Major chord settles out into longer and longer notes values based on...well, you can figure it out. This little etude is called "Fibonacci Frenzy." (Yeah, yeah, yeah, I should record it like a real pianist and not subject you to this robo-performance, but I am appreciating the way Noteflight allows for the embedding of scrolling notation.)



 Since there are only a couple of hours left on this blogday, I'll just add two quick postscripts.
  • In response to my Fibonacci vocal warm-up, Twitter friend Dan introduced me to a very entertaining and ever-expanding piece based on a Fibonacci-esque sequence: Narayana's Cows. This music definitely pushes the limits of how far out we can perceive these expanding connections.
  • Rather coincidentally, this Sound Field video crossed my path a couple of days ago. Early on [0:21-0:40], one of the hosts indulges in some of that mystical "some music sounds right yada yada because...well...Golden Ratio!" As often happens with such discussions, there's not much substantive probing of what's going on and how valid this is aesthetically, though I appreciated some acknowledgement [3:28 - ] that Golden Ratios might just be the kind of thing you can always find if you look in the right place. But, most notably for me, the same host, Nahre Sol, ends the video with a little composition she wrote using both the Golden Ratio to govern the structure and some Fibonacci numbers to generate some riffs. (Oddly enough, the complete composition is not played in this video, so we don't get a chance to experience the Golden Ratio!) If you like hearing numbers dance, you might enjoy this.

    Happy MMmusing Day!
