About Daug9 — 1st inversion
Daug9 is D, F#, A#, C and E — D7 with the fifth raised and the natural ninth added on top.
It sounds bright, tense and slightly unreal. Raising the fifth leaves no semitone in the lower half of the chord, which is where the whole-tone flavour comes from.
Daug9 notes and formula
| D | F# | A# | C | E |
|---|---|---|---|---|
| 1 | 3 | ♯5 | ♭7 | 9 |
Altered dominant — dominant pull with a whole-tone colour.
Also written D9#5, D+9 or D9(#5). The same chord either way; which spelling you meet depends on who wrote the chart.
How to play Daug9
Daug9 in 1st inversion puts F# in the bass instead of D, the 3rd of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
2 of Daug9’s 9 common shapes do this: 232332, 14-15-14-15-15-14.
Start with x70576 — no barre and 1 open string. None of the shapes for Daug9 uses an open string, so every one of them is movable; the lowest sits at the 2nd fret. 4 of the 9 need a barre. Together they cover the neck from the 2nd fret to the 15th.

How to use Daug9
Daug9 is a dominant with its tension raised, so it still points at G — harder than a plain seventh does, because the altered tones sit a semitone from where they are going.

| F#, the major third | rises a semitone | G, the root |
| A#, the sharp fifth | rises a semitone | B, the major third |
| C, the flat seventh | falls a semitone | B, the major third |
| E, the ninth | falls a whole tone | D, the fifth |
