Run it and every other note forms the m6 chord, the engine of his harmonic system. It turns a static minor chord into continuous internal motion.

it consists of these notes and degrees:

tip
  • This is Barry Harris's minor sixth diminished scale: alternate the Bbm6 chord tones with the diminished tones as you climb, chord-tone on the beat.
  • Harmonize every scale step as either the m6 chord or the diminished 7th; that alternation is instant movement over a static minor chord.
  • Use both 6ths deliberately: natural 6th (G) belongs to the m6 sound, flat 6th (Gb) to the diminished layer passing between V and VI.
  • Over a minor ii-V-i in Bb minor, this single scale supplies voice-led chords for the whole bar of tonic minor.

How to play B♭ minor six diminished on guitar

Lowest-numbered root is fret 1 on the A string, so the A-shape barre sits at the very bottom of the neck. Open A gives the major seventh, open G the sixth. Neither is the tonic, so treat them as tension over a fretted root. Both E strings carry a root at 6. Fret 10 marks where the box gives out, which means plenty of room below.
