Wonderful article. I've played piano all my life, except for the first 6 and a bunch of layoff years, and other instruments (woodwinds, strings, percussion, mostly). I understand the others and tune them myself to the extent i can, but pianos are a mystery.

I have to be that guy and remind people that are inspired by this to truck a piano home, that hantaviruses are a thing, sometimes a fatal thing, and mouse droppings are biohazards.
