I have been relearning La campanella over the past few weeks. I am up to the end and I am having difficulty playing without tension in the arms with the fast octaves(mainly where the main theme comes back in with the fast octaves in the right hand). Anyone who has played this piece, how did you get past that? I am trying Hanon (part 3) wrist exercises with thirds, sixths and octaves, It helps a bit but I'm still no Yundi Li. How does Yundi Li play those octaves so *** fast? there must be a way.
