   Since I was completely self-taught on piano, starting by noodling around on the instrument in college, I developed a weird system where I focused on the black keys. By themselves they form a pentatonic scale. But I also liked to spice them up by adding two white keys: one from each space between groups of black keys.

   When I started at C# and included the white keys F and C I got a major scale, namely C# major. I probably knew this, but mainly it just sounded good.
