7. C Whole Tone – Half Tone Scale Chord Diagram
The C Whole Tone – Half Tone Scale Chord Diagram contains 4 diminished harmonies, all with a 4-note base chord and the possibility of up to 4 tension notes (handle with care!).
This of course is very closely related to the Half Tone – Whole Tone scale which presented us with 4 Dominant 7th ♭9 chords.
For convenience note names have been kept the same as Cdim7 in the other 3 columns which means some are enharmonically “unlawful” when related to the root note.
