Interesting! I love everything about how and why the piano came to be. Without numbers on the widths, it's hard for me to grok the article... but I can tell from looking down at my synth that E is the big fattie and has a much wider section between the black keys. You can also stick your finger in there and feel that A is thinner than E, and it feels to me like G is thinner even than A. This is on a Roland V-Synth. It seems like manufacturers can solve this however they want? Is one way predominant?
