As baddox mentioned - gary garrett does this! eg https://www.youtube.com/watch?v=jA1C9VFqJKo https://www.youtube.com/watch?v=jA1C9VFqJKo I have been wondering for a while if it's possible to show both harmonic and melodic relationships at the same time - garett's visualization shows the b7 to 1 movement as a large harmonic leap, but hides the fact that it's a small melodic movement
