Well, jlh, you're right, I should have been more specific...
I won't really be performing like in a recital, it will be more of a background, like a pianist in a restaurant. I will be playing the following...
Bach P&F in A minor, WTC book 1
Beethoven Waldstein (Entire sonata)
Chopin Scherzo No. 2
Liszt Un Sospiro
Gershwin 3 Preludes
I was a little concerned that some of the pieces aren't really suitable for kind of a "background" in some parts, but even though he is a Latin teacher, he is very familiar with classical music, and I told him my current repertoire (above) and he said it would be great!
I know this only totals to about an hour, but I will definitely pick up some things I used to play to add some more time (I think some Debussy would be perfect), and he said I could repeat some pieces, and that some people may even want to hear some things again.
Another very important thing I forgot was to specify American dollars, since this forum is very international.
So I hope that gives you a little more information for your answers. Thanks!
