(a side note: I can (barely) read music, and I really enjoy looking at piano scores, even if I can't come close to playing them. For some reason, I find them beautiful in their own way)
Of course, writing down a collection of the hardest notes to play doesn't make something music, but playing it does (YouTube video), at least in some respects. Listening to this piece is almost (but not quite) like listening to someone banging on a piano as fast as they can. It's the not quite that gets you. The piece is incredibly dissonant, and really hard to listen to as music. The movement and range is ridiculous, if you can even call it movement and not banging. But the difficulty is that at the end of the day, like John Cage's 4'33", we must admit that it at least resembles music.
