Polytonal Chords
This technique allows you to create a bigger tension chord by playing two different chords in a row arpeggio style. Remember to play low to high in tone - starting with the low tones on the left to the higher tones going right.
The first examples are major arpeggios created from the C major scale.
Every note position in a major scale is assigned a coinciding number position.
Example given in key of C major. Number positions are the same for all fifteen keys.
C major note names = C, D, E, F, G, A, B, C, D, E, F, G, A, B, C
C major scale numbers = 1/R, 2, 3, 4, 5, 6, 7, 8/R, 9, 10,11, 12, 13, 14, 15/R
C major seventh - C, E, G, B
D minor seventh - D, F, A, C
Together = C, E, G, B, D, F, A, C = C major thirteenth or Cmaj13
Number formula = R, 3rd, 5th, 7th, 9th, 11th, 13th
C major sixth - C, E, G, A
B minor seventh flat fifth - B, D, F, A
Together = C, E, G, A, B, D, F, A = C major sixth add seventh, nine, eleventh and thirteenth or
Cmaj 6/7/9/11/13
Number formula = R, 3rd, 5th, 6th, 7th, 9th, 11th, 13th
C major seventh - C, E, G, B
G seventh third inversion - F, G, B incomplete
Together = C, E, G, B, F, G, B = C major seventh add eleventh or Cmaj7/11
Number formula = R, 3rd, 5th, 7th, 11th
F major sharp eleventh - F, A, B
F major - C, E incomplete
Together = F, A, B, C, E = F major seventh sharp fourth or Fmaj7#11 (also written Fmaj7#4)
Number formula = R, 3rd, #4, 5th, 7th
Assignment: Record each of these chords (last chord given in each example) - using quarter note strums for five to ten minutes. Then using quarter then eighth notes on another track or with a friend - play the bi-tonal arpeggio up in tone then down in tone.
Now transpose these to each position (register) of your instrument, then to all 15 keys.
