Isn&#x27;t this pretty much what musicians do anyways? When I was learning how to play piano as a kid the exercise books basically would take one pattern, make you learn it over the keyboard, and then the next exercise would be a slight variation on the previous one. Enough that you had to spend time with it, but not completely different than the last exercise.<p>All musicians I know do the same: scales, pattern exercises, and songs of increasing difficulty.
