You should try out Schubert's impromptus (no.2 or no.4), or take a sonata like Beethoven's op.10 no.1 or Mozart KV309 in c major (this one is easier). What do you think?
Thanks for the help. I listened to them. I kind of like how impromptu no.2 sounds best. The Beethoven sonata you recommended was free on here though, so I printed it out and started playing a little. I didn't care for the sound of the mozart though.It's kind of funny though. I listened to them and thought they sounded complicated. Then looked at the sheet music and they look so much simpler (but still a challenge).
