I mentioned this to my teacher last lesson (about a week ago) and he was suitably concerned, but after watching me play could only suggest that I was maybe too tense about the whole piece. Which I was, since I was trying to get it all perfect from the word go
From looking at my hands when playing, I think the problem may be that I'm struggling with the stretches involved between 1-2 and 1-3 in particular, and that in order to get my thumb securely on to the black keys (the piece being in 4 flats), I'm tending to flex my wrist laterally and also stretching my fingers quite flat, which produces the pain down the outside of the wrist and forearm. I've tried keeping my hands reasonably square to the keys (and curving the longer fingers), but then I can't make the stretches.
Any ideas at all about (a) whether the 'diagnosis' above sounds plausible, and (b) if so, what I can do about it?? I don't have another lesson for at least a week, and I don't want to have to give up practising until then. I had a look through the Hanon and have tried some of the exercises which suggest that they deal with 1-2 and 1-2-3 extensions, but they don't seem to involve anything like the kind of stretches which the piece itself requires.
I'm not old enough for it to be incipient arthritis (I hope) and I don't have tiny hands; I also didn't think I had particularly inflexible hands, but maybe they're stiffer than I realise?
