I wouldn't call myself a Chopin addict, but he is easily one of my favorite classical composers (along with Debussy and Rachmaninoff). I won't pretend that I know that piece, because I don't. Haha. My favorite piece by Chopin is his "Black Key" Etude (the Etude in G-flat). Although I can't play it.
Sounds tough. Good luck with that. Do you play with an orchestra? Or like, with a school octet or something? I'm not really sure how those types of things work. And I can think of worse ways to spend a summer. Getting a job at McDonalds is one of them. As for my summer, I'm probably going to be pondering college... stuff. You've just managed to breach high school, but I have to worry about college. Ugh.
