berrt, thanks for listening. And I hope very much that the audition room is a source of learning and inspiration and not one of frustration! Keep playing and enjoying the music!!
can I ask you something? about the technical difidulty on playing it. How dificult do you think it is? (maibe using mozart piano sonatas as a reference for comparison) . thanks in advance!
piano121, I can only comment on the technical difficulty of the piano part. If it's also about the violin, I'd have to ask my friend (but I know that she practiced less than I did... :-)). I have played the C (K. 545), A (331), G (283) and a (310) solo sonatas so far -- this order reflects increasing difficulty in my impression. I would put both 301 and 304 close to 331, with 304 (e) a bit easier than 301 (G).
I hope this will encourage you to give it a try! Good luck, and in case I might be able to give some specific tips let me know. Btw, there are ~15 Mozart piano+violin sonatas, some others might be even easier. Also, have a look at the Schubert p+v sonatinas (in fact Schubert called them sonatas) which are wonderful pieces and even easier than 301 and 304.
Update: I just read in another thread that you're playing Chopin FI. So you can definitely go for these two here!
