Wow, definately non-Nico!
Sonata No. 48 -
Such a great romantic piece! This is a somewhat modern piece, I would say. I threw in "somewhat" because I would not say it is purely modern, as it still sounds good to my ear (I'd image you'd say the same). Clever piece. It's way above my head musically, since I've only been composing for two weeks or so. Thus, I'll just say, very nice and energetic! Did you compose it for a reason? Oh gosh, there's no ending to the piece. Well, almost congrats, but not really
Duet -
Again, you are a much better composer than I, and it would be an insult if I tried to "constructively criticize" your work. This also is a fun and energetic piece, and is very nice to listen to.
Good luck and keep composing...well,
Evan
