What about Chopins Ballade No. 1 in g minorWhen I saw the movie 'The Pianist' - and I saw the piece being played - I almost cried... (You'd need to see the movie to find out why.)
I played that polonaise (op.40 no.2) , it is quite easy. I dont see why you hate "overplayed" pieces, because for me some of the pieces you mentionend as overplayed sure aren't to me. I guess the op.44 polonaise (f sharp minor?) is too hard. Why must you play Chopin for the romantic piece? You can play Brahms, Schubert, Liszt...Well, im not sure if Schubert is counted in it but if you choose something from him, I love his impromptu in E flat major (op.90 no.2?). From Liszt, you could try a piece from his Années de Pelerinages, or from Brahms one of his rhapsody. (although they are pretty hard).
Having played both Op.26 No.2 and Op.48 No.1, I'd unhesitantly label the nocturne the more difficult of the two by far - it's my favourite Chopin nocturne, and I agree that the last section is incredible, but that last section is also technically blistering. If you can pull it off, though, the judges should be duly impressed! The polonaise isn't nearly as difficult but it's one of the more repetitive of the polonaises - Motrax makes a good point about the repetition of the polonaises making them somewhat problematic (my teacher in high school, a graduate of the music school at Indiana in the 1970s, didn't assign the polonaises to his students for this very reason). I like the Op.26 No.2 polonaise (especially the middle page of the E-flat minor section), but there are perhaps better choices even among the polonaises. Phil, I see from your other thread on the repertoire for your auditions that you do have the Op.40 No.2 polonaise partially learned, polishing it to audition standards shouldn't take long.But I do have to agree with Motrax that the Op.51 impromptu might be the best choice of all - not only does it not repeat itself to the degree of the polonaises, but it's also one of Chopin's most underplayed mature works (the liner notes to my recording of Rubinstein playing the Impromptus and More Besides cites the difficulty as being responsible for its lack of exposure, but this seems misguided), which I think is a real shame as it's one of my favourite Chopin works.
Do you have any other comments for the rest of my audition, mlsmithz? Post on the other thread, if you do, I could use all the help I can get.
It seems like whenever I take a piece off the list, another finds its way in. Maybe I like Chopin too much ...
