But, it did turn out to be Strauss, and as I was driving along, it occurred to me that Beethoven had already supplied the first phrase of "Somewhere" in the slow movement of the "Emperor" Concerto. (That's a pretty commonly made observation.) I knew then it was my job to go home and stitch the Beethoven and Strauss together into a little Bernstein. I wasn't surprised to find that others have also cited the "Somewhere" connection in the Strauss, most notably in this YouTube video, which cleverly pairs Glenn Gould's discussion of the Strauss with Barbra Streisand's rendition of the Bernstein. ("Clever" because Gould was a big fan of Streisand.) Still, I wanted a real mashup.
Because I was so eager to get right to it, I went straight to the second half of the Burleske, found the tune, and discovered that the Beethoven and Strauss components were a full tritone apart. Unfazed, I found that by transposing Beethoven down a m3 and Strauss up a m3, I could get them to match without the audio sounding too muddled from the pitch-shifting. Only as I began writing this post did it occur to me that maybe I should listen to the whole Burleske to see when and how else the tune is used. Well, wouldn't you know, the tune appears early on IN THE SAME KEY AS THE BEETHOVEN! (Technically the Beethoven's in B Major and the Strauss is in G-sharp Minor, but same key signature and, most importantly, same notes in the tune.) Quite a "coincidence," Mr. Bernstein! So, if I'd just done my research first, I would've saved some time.
Anyway, here's what they sound like together:
Here's what the Strauss tune sounds like in broader context.
You can listen to the complete Burleske here and here.
And here's how my first mashup came out - the one where I had to transpose the two tunes. I like it because the cellos play along with this second statement of the Strauss tune. So beautiful.
