Hello all,
In about 10 months time I plan on auditioning for a music school. I need to have prepared a program of two contrasting pieces, and 3-4 short items of technical work (studies, scales, ect). My audition can be no longer than 15 minutes.  Unfortunately that's the only information I've been able to get regarding repertoire for my audition.
So: I'm currently working on the Beethoven sonata no 1 in F minor, Beethoven sonata no 14 in C sharp minor (Moonlight), Chopin Etude Op 25 no 11, and a Liszt Paginini Etude no 5 ("La Chasse"), and have recently "finished" (more or less; obviously one can never truly finish a piece) the Chopin Nocturne Op9 no 2, and the Mozart sonata Kv 309.
Due to the short time allowance, I realise that none of the sonatas will really work for my audition. So would anyone be able to give me a few suggestions regarding what could work? Perhaps particular movements or something? Or just other pieces that would fit my time allowance and make an impact. Also which etudes i should use (and any others that could be worth learning- I do have quite a bit of time to prepare)?
I have been learning piano for 8-9 years now with teachers- of course, you may say "why don't you just ask your teacher?" but I will be moving back to my home country in a few weeks so now isn't the ideal time to be starting new pieces with my teacher here (but there is nothing wrong with thinking  about it now).
Thanks
