The minor six-nine chord combines a minor triad with 6 and 9 (1-♭3-5-6-9). It is famously associated with quartal voicings in modern jazz (stacked fourths that spell the same pitch classes) because it sounds stable yet open—perfect for modal vamps. The added ninth widens the stack while the sixth keeps warmth on top of the minor third.
Construction
Think m6 plus 9, or m(add9) with 6. In Cm69, color tones include C-E♭-G-A-D before voicing choices.
Usage
Minor modal grooves, punchy stacks in small-group jazz, and neo-soul pads where you want clarity without a seventh.
Examples
- McCoy Tyner–style fourth stacks on minor roots
- Modal vamps on i69
- Modern funk keyboard ostinatos
Play
Quartal voicings are idiomatic; keep the bass root defined so the chord does not float too ambiguously.
Ear-training cues
Minor triad with 6 and 9 extensions—open, modern, percussive potential.
