Fingering charts
The library holds 8 fingerings of this chord and all of them are shown, in the library’s own order. Several fingerings of one chord is normal: the same notes can be stopped at different positions and on different strings.
Formula
The chord tones in order from the root, with the interval each one forms above it.

|---|---|---|---|
| 1 | Db | 0 | Perfect unison |
| 3 | F | 4 | Major third |
| 5 | Ab | 7 | Perfect fifth |
| 7 | C | 11 | Major seventh |
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 | Db | 1 | Db – F – Ab – C | 0 4 7 11 |
| first inversion | F | 3 | F – Ab – C – Db | 0 3 7 8 |
| second inversion | Ab | 5 | Ab – C – Db – F | 0 4 5 9 |
| third inversion | C | 7 | C – Db – F – Ab | 0 1 5 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 | 9-8-10-10-9-8 | Db F C F Ab C | 1 3 7 3 5 7 | Db | 2 | 6 |
| 2 | 9-8-10-10-9-9 | Db F C F Ab Db | 1 3 7 3 5 1 | Db | 2 | 6 |
| 3 | 9-11-10-10-9-9 | Db Ab C F Ab Db | 1 5 7 3 5 1 | Db | 2 | 6 |
| 4 | 9-8-6-6-6-8 | Db F Ab Db F C | 1 3 5 1 3 7 | Db | 3 | 6 |
| 5 | 9-8-6-6-9-8 | Db F Ab Db Ab C | 1 3 5 1 5 7 | Db | 3 | 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.
