Cool Piano Fact: Piano and Symmetry

Here’s a cool fact you probably never noticed about your piano: Did you know it’s symmetric? It doesn’t look like it at first glance. You have the black keys arranged in groups of two and three, but that’s just because you’ve been looking in the wrong place. I’ll show you how your piano is a mirror image of itself when looked at from the right pivot point. This lets you construct neat exercises and double melody lines in interesting (and often quite odd) ways!
