play "The Swan" on the theremin

I recently made a cellist friend who says he’ll hook me up with sheet music, which I shall then be able to memorize with, I think, little trouble.

I’m good for the first nine notes, but then I taper off. So far the largest impediment to achieving this goal is that, like, I think, most people, it’s tough for me to accurately memorize an instrumental piece. And since there are no physical reference points on the theremin, unless you have perfect pitch (which I obviously don’t), you really have know the music by heart before you can play it.
