I adore the Chopin Barcarolle that I've started learning. You can watch a video of Krystian Zimerman playing it below (complete with crystal chandelier so that you know you're listening to Important Music). A barcarolle is a Venetian boat song, and as such, is generally written in a rocking, lulling 6/8 meter. What I don't understand, though, is why Chopin had to choose F-sharp Major as the key for his barcarolle. That's six sharps in the key signature, which means playing almost entirely on the black keys, and worse, whenever there's an accidental (which is like, always) the result is a double-sharp. I find myself constantly doing complex mathematical equations in my head to figure out what I should actually play. Not really, but I like to whine. Anyway, I can't think why the piece would be any less boatlike had Chopin started us out a half step down, F major. One lousy flat, that's all we would have had to deal with.
Yes, I realize this is only a legitimate gripe if you're an intermediate junior high pianist. But still. I have things to do, Chopin.
