Are there (technically) easier and harder keys? Does it sometimes happen to you that, when confronted with a new piece you like to learn, you see the key and go: "Jeez, why did the composer put this lovely piece in x-major or y-minor? Such an unpianistic key!!" Or, alternatively: "Oh great, I love x-major or y-minor!"
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?
