[jannis123321]

Hey,
im currently working on the Symphonic Etude VI and would like to hear your tips, suggestions and experience, which you had practicing this fenominal piece, especially when it comes to gaining speed and the "big jumps" in the left hand.   

In addition to that i would apprecaite, if one gave me his opnion in regard to the difficulty of this piece, compared to the other Symphonic Etudes / Variations.

Faithfully
