It's definitely better on the piano than on string instruments though. You also don't get repetitive strain injury as quickly. I don't think I've ever managed to get any pain by playing the piano alone. (I had RSI once, but that was mostly because of the computer, not the piano). Oh, and the half piece of Vexations is just for one hand, so you can always rest the other a bit, or use it to drink some water or something
