i'm still terrible at keyboard, but my improvisation has gotten a lot more musical sounding, because i tend to place my fingers so that they have nice intervals between them like 3, 4 or 7 semitones, or sometimes 2

‪oh and i stay within some kind of improvised scale while doing that‬

‪i never learned the standard scales in a proper fashion, but it turns out that if you know the pattern in your head of how many semitones there should be between things, and get into the habit of counting them out, eventually you get used to the finger placements anyway…‬

‪the aebersold blues scale isn't really a scale but it was fun enough to play with that it got me into the habit of transposing scales, which i wouldn't otherwise be interested in doing, and i think that's improved my keyboard skill‬
