Hey, I think it's way more awesome to play the octave, then switch hands in the op 10 no 1. It's not what chopin wrote or intended, but lets do that anyway. And I don't really like the thirds in the 4th ballade, so I only play one voice... Seems reasonable, eh?
He obviously wrote legato. Why the * would you think it's a good idea to play it non-legato?
the 4th in op 10/4 is also rather lame, I think I play them with the left hand. And the middle voice in op 10/2 is also lame, so I probably just.. well, don't play them...
