Faug — F augmented chord
Root, major third and augmented fifth: two stacked major thirds. Because the thirds are equal the chord divides the octave into three, so it has three enharmonic spellings and only four distinct forms.
- 1 = F
- 3 = A
- #5 = C#

Formula
The chord tones in order from the root, with the interval each one forms above it.
| Degree | Note | Semitones | Interval from the root |
|---|---|---|---|
| 1 | F | 0 | Perfect unison |
| 3 | A | 4 | Major third |
| #5 | C# | 8 | Minor sixth |
Inversions
An inversion is the same set of notes with a different one in the bass. The last column gives the distance of each note above the bass note, in semitones.
| Inversion | Bass note | Degree in the bass | Notes above the bass | Semitones above the bass |
|---|---|---|---|---|
| root position | F | 1 | F – A – C# | 0 4 8 |
| first inversion | A | 3 | A – C# – F | 0 4 8 |
| second inversion | C# | #5 | C# – F – A | 0 4 8 |
Playable voicings
These shapes were found by searching the fretboard of a standard-tuned guitar (E A D G B E) rather than copied from a chord book. The search allows every string to sound or to be muted, rejects any shape with a muted string between two sounding strings, rejects any shape whose fretted notes span more than four frets (a five-fret window), requires every chord tone to be present, and then sorts what remains with root-position shapes first and the most compact, lowest shapes next. The shapes shown are the first six of that ordering; other orderings are possible at the same frets.
| # | Shape (low string first) | Notes | Degrees | Bass | Span (frets) | Sounding strings |
|---|---|---|---|---|---|---|
| 1 | 1-0-3-2-2-1 | F A F A Db F | 1 3 1 3 #5 1 | F | 3 | 6 |
| 2 | 1-4-3-2-2-1 | F Db F A Db F | 1 #5 1 3 #5 1 | F | 3 | 6 |
| 3 | 13-12-11-10-10-13 | F A Db F A F | 1 3 #5 1 3 1 | F | 3 | 6 |
| 4 | 13-12-11-14-14-13 | F A Db A Db F | 1 3 #5 3 #5 1 | F | 3 | 6 |
| 5 | 13-12-15-14-14-13 | F A F A Db F | 1 3 1 3 #5 1 | F | 3 | 6 |
| 6 | 1-4-3-2-2-5 | F Db F A Db A | 1 #5 1 3 #5 3 | F | 4 | 6 |
Shape numbers run from the lowest string to the highest, so the left-hand number is the sixth string (low E) in standard tuning. Multiple shapes are listed because a chord can be voiced several ways, and because a lower position is not always the better sounding one.
