Triads in the Diminished Scale
(08 May 02)
Triads that are derived from the diminished scale are an interesting improvisational tool. They allow you to create the effect of playing 'in' and 'out' of a key.
There are two diminished scales in C:
1) half-whole tone scale
C7 (1,3,5,b7) + all tensions b9, #9, #11, 13
C7alt, C7(b9), C7(#9), C7(#11), C7(13), C7(b9,13)....
Cdim (1, b3, b5)
Cm7(b5) (1, b3, b5, b7)
2) whole-half tone scale
B/C (1, b3, b5,maj7)
D/C (1, 9, #11, 13)
In general, the best way to make them sound good is
- to play the chord tones on the strong beats
- to finish a phrase on a chord tone
The diminished half-whole tone scale, as a sound, is easier to use. The reason is that there are the major third, the minor third and the natural fifth in the scale.
