I can play Fantasie Impromptu op.66, Minute Waltz, I`m practising Polonaise in Ab Maj op.53.
Generally, I don`t have problems with `jumping`with my left hand and my RH is also quite fast. What piece can I begin to play? It doesn`t have to be Chopin? Something beetwen those pieces and Ballade in G Min.

well...in between....i would say..a few of his etudes..and some of his preludes....but for harder..the polonaise brilliante is harder..and the hardest polonaise is the polonaise fantasie...

thanks
