So 53, maybe you can help me with a little problem I'm having. Whenever I play Kate Martyn's Waltz, I find that in the B part, the fingers of my right hand (the keyboard side) get cramped up, and I have difficulty stretching them out enough to play the notes correctly. Maybe it's a carpal tunnel problem. I don't know. It never used to happen, but these days I find I can't play that waltz any more because of it.
