Watch the Harmonic Minor Scale online guitar lesson by John Stowell from Modern Jazz Improv
I'm using the same four modes (7th, 2nd, 4th, 5th) and key centers (1/2 step above, whole step below, 4th and 5th above) of harmonic minor over dominant as I used for the melodic minor. I think the harmonic minor a half step above might be the hardest to integrate of the four because the 6th (13th) is now in the equation with all of the tensions (#9/ b9, #5/ b5). I've found that moving down chromatically from the 6th to the b6th makes more sense musically than moving up from a tension to a consonant note in the scale. Notice that I'm using harmonic minor chord voicings (maj 7th w/b6,9,11,b13) as altered dominant chords here.
