No - not stupid atall! Have you ever tried playing the black key etude of Chopin.
To give a few examples: I like E major, B major, Dflat major, Aflat major. To me, these are pianistic, comfortable, "forgiving" keys. I don't like: Bflat major, Eflat major, D-major or A-major. Any thoughts on this?
If you notice the natural hand form Chopin considered i.e: FGbAbBbC RH and EGbAbBbC LH, this is considered the most comfortable position for the hand since all the middle fingers are on black notes which offer great support/balance to the hand.
