The root left to the bass player. Frees a finger for a tension.
D69 is D, F#, A, B and E — D6 with the ninth added as well.
It sounds wide and entirely at rest. The modern way to voice a tonic when a triad is too bare and a maj7 too pointed.

| D | F# | A | B | E |
|---|---|---|---|---|
| 1 | 3 | 5 | 6 | 9 |
Tonic — it commits to nothing.
Also written D6/9, D6add9 or D six nine. The same chord either way; which spelling you meet depends on who wrote the chart.
Leave the root to the bass player. In a band nobody misses it, and the ear supplies it from the guide tones anyway.
The finger it frees goes to a tension, which is why these sound richer than the shape they came from rather than thinner.
D69 has 13 of them, on the top four strings, the middle four strings and strings 5-3-2-1, from the 2nd fret up to the 12th — every inversion the chord has: F# in the bass, A in the bass, B in the bass and E in the bass. The one to learn first is the E shape at the 2nd fret, which is the easiest grip here.
5 of them sit on the top four strings, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with x54200 — no barre and 2 open strings. 1 of the 9 shapes here sits in open position. 7 of the 9 need a barre. Together they cover the neck from the 2nd fret to the 15th.

The same notes rebuilt from scratch give 3 shell, 12 drop 2, 8 drop 3 and 6 open string voicings, each on its own page.
Tensions. A shell of D69, root, third and seventh, leaves a string free, and the tones that belong over it are the #11 (G#).
How you get to it. The turn that lands on D69 is Em7 to A7 — the ii and the V of D — and A7 shares its third and seventh with Em7, so the hand barely moves between them.
In which keys. Every note of D69 belongs to D major (the I), E minor (the ♭VII), F# minor (the ♭VI), G major (the V), A major (the IV) and B minor (the ♭III).
D69 is every note of the D major pentatonic, and nothing else. It also sits inside D major, D lydian, D mixolydian and D lydian dominant.
Change one note of D69 and you have Dmaj9 (the sixth becomes a major seventh), Dmaj13 (add the major seventh), Dm69 (the major third becomes a minor third), Dadd9 (drop the sixth), D6 (drop the ninth) or D9 (the sixth becomes a flat seventh).
D69 is a major chord — root, major third, fifth. Major chords on every root.
On D69’s sound and use this page follows Mark Levine, The Jazz Piano Book (Sher Music, 1989). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
