I'm in love with all the pieces I'm learning right now!
Especially Bach's French Suite no 5 (the Allemande)... it is just so pretty and I can just imagine myself in like... 18th century France! Oh and I like Chopin's nocturne op 27 no 1, it just seems to match my emotions so well when I'm upset ... I love it more every time I play it. Although I can't play either piece very well yet.
As for pieces I want to play, there are too many! Probably some Rachmaninoff. I can only play one of his pieces, the Etude Tableau op 33 no 8. Which is also really beautiful! But I like most pieces by Rachmaninoff, there's no way I can single one out! It's just that my teacher doesn't want me to play most of them, because a) they're too difficult for me and b) Rachmaninoff had big hands

And I'm really loving Ornstein's Arabesques right now.
