YA book where main character beats some sort of video game(?) by memorizing the exact movements and associating them with a piece of classical music.

I think this was a book (it’s possible it was also a move or tv show though). I think I remember it being set in the real world, maybe a futuristic version? Literally the only other thing I can remember is that this game the character beat was considered super hard or impossible, and the main character did it perfectly with this memorization technique. Like every action they took was set to the rhythm of the music they found that fit perfectly.

When did you read it?

Was the main character male or female?
