When I get frustrated with a piano piece, I sometimes wonder are we limited by the keyboard layout (i.e. groups of 2+3 black keys on top of the white keys)?
Since the keyboard layout was invented, we have stuck with it and continued producing keyboards like this without thinking if maybe we could improve upon it.
What do you think? Is it an arbitrary choice or do you think it's the best we can do?
I didn't find the right solution from the Internet.
