About Faug9 — 1st inversion
Faug9 is F, A, C#, Eb and G — F7 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.
Faug9 notes and formula
| F | A | C# | Eb | G |
|---|---|---|---|---|
| 1 | 3 | ♯5 | ♭7 | 9 |
Altered dominant — dominant pull with a whole-tone colour.
Also written F9#5, F+9 or F9(#5). The same chord either way; which spelling you meet depends on who wrote the chart.
How to play Faug9
Faug9 in 1st inversion puts A in the bass instead of F, 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.
One of Faug9’s 7 common shapes does this: 565665.
Start with xx1223 — no barre and down at the nut. 1 of the 7 shapes here sits in open position. 4 of the 7 need a barre. Together they cover the neck from the 1st fret to the 14th.

How to use Faug9
Faug9 is a dominant with its tension raised, so it still points at Bb — harder than a plain seventh does, because the altered tones sit a semitone from where they are going.

| In Faug9 | Moves | In Bb |

| F, the root | stays where it is | F, the fifth |
| A, the major third | rises a semitone | Bb, the root |
| C#, the sharp fifth | rises a semitone | D, the major third |
| Eb, the flat seventh | falls a semitone | D, the major third |
| G, the ninth | falls a whole tone | F, the fifth |
