Chopin wrote his music to be comfort to the hands! I can't understand you...
I think his music requires much flexibility on arms and shoulders, and having stiffness on those areas leads into tension in hand and wrist. Unfortunately I have not yet been able to get rid of the upper body stiffness (and maybe never will completely) because of structural issues.
I don't think anyone is in doubt about my answer. Must I say it? All right...RACHMANINOVand no one else!
Chopinīs music is very unpianistic, compared to Beethoven for example.
