I have read that Chopin was fond of Hummel, and I've always sort of wondered why, since the only Hummel composition I have ever been familiar with is the trumpet concerto, which seems to be very different from Chopin's style (it's very much a Wiener Musik type of piece).
Well, we had a lecture in Vienna today with a lady who wanted to turn us on to Hummel, since he's a relatively ignored composer, which she thinks is unfair, and she played a serenade (don't remember the exact title?) for piano, violin, clarinet, and bassoon (? - I know those instruments were involved, and it ended with an arrangement of Mozart's
Le Nozze di Figaro overture), and I could really hear a great deal in the piano part that could obviously have influenced Chopin.
So, now I'm interested in playing something by Hummel, but I'm very ignorant about his piano repertoire. Any suggestions? I think my teacher will allow me to contrast Hummel with Chopin, which would be convenient, because I always struggle with choosing the non-Chopin/Bach pieces for my juries and recitals.

Something large-scale like a sonata would be awesome, but not too terribly difficult, as I'm really just amateur in skill. I can play difficult things, but it takes a lot of work.
