Guitar
 

I am learning classical guitar at school, just picked up the peice Fur Elise by Bethoveen, it is great, learned half of it in one week, memorized, so I find it beautiful and peaceful to my normally tense mind.

Yeah for some reason a good portion of the "major" composers of the period didn't write so much for guitar, but if you want to try some pieces, try looking up Anton Diabelli and Pietro Pettoletti. They have written some really good authentic-period (Classical to early Romantic) pieces geared for guitar

There are some great classical guitar pieces , that are written from Bach.
