Major 6th chords

For BH, Major 6 cords have an extra #5/b6 note (making playing it with all the tensions and chord note an octatonic scale with an in-built diminished 7th between the 2nd and 7th degree.

So:

Maj7: R/1 9 3rd 11 5 #5!/b13 13 7 R
Within: from the 9th to the 7th, there’s a diminished 7th chord a semitone down away
(Where M=Major chord tone, m=minor)

With the appropiate voicings you can then:

Extra half-step rules

  1. Descending lines: If you start at the root, 3rd, 5th or 7th you can put an extra half-step after these.
  2. 2nd, 4th or 6th means no half-steps.
  3. You can also put two half-step.
