What is the meaning if the piano player likes to "choke up" on the white piano keys (i.e. press them well in between the black keys, close to the backboard). I do this, and I never noticed it was distinctive until someone commented to me about it. Due to leverage, the keys require more force to press back there, but that's what I like.
Too much testosterone! This is the sign of a dangerous piano player. Never in all my days would I have suspected such. We had better measure your fore and ring fingers. If the finger test checks out, the women shrinks had better get you on estrogen therapy.
