I'm boggled at the thought of your teacher rejecting the Pastorale sonata and op. 7, but not op. 57. In any case, if he is suggesting the Appassionata, why not take his advice? It is a good piece with which to be familiar anyway.MikeP.S. With whom are you planning to study at IU? I did my undergrad there.
Ah, but Pressler may be among the audition panel. And I've heard he's thrown kids out of masterclasses for playing late Beethoven Sonatas without the musical maturity required. Someone once told me that Beethoven Sonatas and Schubert Sonatas are incredibly difficult and one does not reach the maturity required to play them until their 30s. Due to my inexperience, I want to avoid the late Beethoven Sonatas.
That only is that story about Mr. Pressler most likely apocryphal, but this bit about not being able to play late Beethoven and Schubert until one's 30's is nonsense.
Well of course, it's possible to play these pieces before one is 30, but truly understanding them takes a bit more than just thousands of hours in a practice room and natural talent. He told me that these sonatas are far more difficult than any Liszt etude or Rachmaninoff or Prokofiev Concerto.
