I was miserable for most of my piano lessons (I learned to sheet read well – I become a fairly adept piano-playing robot – but I never sort of "figured out" music more generally.) That said, one lesson my teacher played a basic blues chord progression and told me to hit anything on the blues G scale however I wanted. That was one of the most fun times I've had making music ever. Well, the only time that has been fun, actually.

If you want to do this with someone who doesn't play, the experienced person can play in Eb and then the black notes make an Eb blues scale.
