This perspective also works for Dominant Chords.



Lets use the G Dominant Chords - using four note chords


G7th = R, 3rd, 5th, b7th G, B, D, F - two chords lie within the G7th chord:
G, B, D = G major and B, D, F = B diminished.


(So the Bass player could play the G note, the keyboard could play G major chord (G, B, D) and the guitar could play B diminished (B, D, F) across the neck to solo or make melodies arpeggio style).


Now lets look at other dominant chords and apply the polytonal approach:


G dominant 9th = R, 3rd, 5th, b7th, 9th G, B, D, F, A
G, B, D = G major and D, F, A = D minor


G dominant 11th = R, 3rd, 5th, b7th, 9th, 11th G, B, D, F, A, C
G, B, D = G major and D, F, A = D minor


G dominant 13th = R, 3rd, 5th, b7th, 9th, 11th, 13th G, B, D, F, A, C, E
G, B, D, F = G seventh and F, A, C, E = F major seventh




This also works for altered dominant chords:


G dominant 7th/b9 = R, 3rd, 5th, b7th, b9th G, B, D, F, Ab
G, B, D, F = G seventh and D, F, Ab = D diminished.


G dominant 7th/#9 = R, 3rd, 5th, b7th, #9th G, B, D, F, A#
G, B, D, F = G seventh and D, F, A#(Bb) = Bb major.


G dominant 7th/b5 = R, 3rd, b5th, b7th, G, B, Db, F,
G, B, Db = G#11 and B, Db, F, = Db (C#) seventh.


G dominant 7th/#5 = R, 3rd, #5th, b7th, G, B, D#, F,
G, B, D# = G#5 and B, D#, F, = B#11.








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.


As always transpose to all fifteen keys.
