I've ordered the Henle edition, and it should be arriving sometime soon.
In the meantime, I've talked with my teacher about the piece, and he told me that, although the variations do get more and more pianistic, the hardest variation is actually in the middle- Variation 13.
He showed me two ways to execute the staccato 32nd notes- one is through wrist motion and the other through finger motion. How would one go about learning this passage? Does the type of motion you use depend on the tempo you take it at?
Also, more comments and suggestions are, as always, welcome.
