Hello. I'm new to these forums, as you can probably tell. I've been working on the revolutionary etude for about six months now (I graduated college, and since, I haven't had a teacher to help me along), and I can play through it at speed, but not at once. Around measure 33 (right hand is on a G#7 chord), I start getting cramps in my forearm, and I can't focus until around measure 45 or so. This is fine, until I get further into it with the polyrhythms on the main theme and my forearm just says, "no!" As I said, I can play through each section individually, but keeping up with it, my arm just gives way. Any tips would be wonderful. Thanks.
