> fighting piano keyboard

Interestingly this is a strong thing to fight because there are pieces of music that are physically inaccessible to many players, particularly people with hands not wide enough for the intervals. No amount of practice or stretching can overcome it and you can't exactly travel with a piano or keyboard everywhere.

There some cool things like the Janko keyboard that seem strictly superior to the traditional 12 keys but it's kind of an uphill fight to build conversion kits cheap and light and good enough to travel and perform with.
