This perspective also works for all the other scales and modes previously covered (see archives bottom of this page).
Lets go back to the C Harmonic Minor Family of Chords - using four note chords (every other note in a group of four notes)
C minor major 7th = R, b3rd, 5th, 7th C, Eb, G, B - two chords lie within the C minor major 7th chord.
C, Eb, G = C minor and Eb, G, B = Eb augmented.
(So the Bass player could play the C note, the keyboard could play C minor chord (C, Eb, G) and the guitar could play Eb augmented minor (Eb, G, B) across the neck to solo or make melodies arpeggio style).
Now lets look at all the other diatonic created family of chords for C Harmonic Minor and apply the polytonal approach:
D minor 7th b5 = R, b3rd, b5th, b7th D, F, Ab, C
D, F, Ab = D diminished and F, Ab, C = F minor
Eb major 7th sharp 5 = R, b3rd, #5th, 7th Eb, G, B, D
Eb, G, B = E minor and G, B, D = G major
F minor 7th = R, b3rd, 5th, 7th F, Ab, C, Eb
F, Ab, C = F minor and Ab, C, Eb = Ab major.
G dominant 7th = R, 3rd, 5th, b7th G, B, D, F
G, B, D = G major and B, D, F = B diminished.
Ab major 7th = R, 3rd, 5th, 7th Ab, C, Eb, G
Ab, C, Eb = Ab major and C, Eb, G = C minor
B diminished 7th = R, b3rd, b5th, bb7th (6) B, D, F, Ab
B, D, F = B diminished and D, F, Ab = D diminished
Assignment: Record each of these chords - using quarter note strums for five to ten minutes. Then using quarter then eighth notes on another track or with a friend play the first, then second polytonal chord up and back arpeggio style. Later combine the scale (harmonic minor) with the arpeggio for more interesting sounds.
Now transpose these to each position (register) of your instrument, then to all 15 keys.
