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.
| Degree | Note | Semitones | Interval from the root |
|---|---|---|---|
| 1 | Db | 0 | Perfect unison |
| b3 | Fb | 3 | Minor third |
| b5 | Abb | 6 | Tritone |
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 – Fb – Abb | 0 3 6 |
| first inversion | Fb | b3 | Fb – Abb – Db | 0 3 9 |
| second inversion | Abb | b5 | Abb – Db – Fb | 0 6 9 |
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 | 9-10-11-9-8-9 | Db G Db E G Db | 1 b5 1 b3 b5 1 | Db | 3 | 6 |
| 2 | 9-7-5-6-5-9 | Db E G Db E Db | 1 b3 b5 1 b3 1 | Db | 4 | 6 |
| 3 | 9-7-5-6-8-9 | Db E G Db G Db | 1 b3 b5 1 b5 1 | Db | 4 | 6 |
| 4 | 9-7-5-9-5-9 | Db E G E E Db | 1 b3 b5 b3 b3 1 | Db | 4 | 6 |
| 5 | 9-7-5-9-8-9 | Db E G E G Db | 1 b3 b5 b3 b5 1 | Db | 4 | 6 |
| 6 | 9-7-11-9-8-9 | Db E Db E G Db | 1 b3 1 b3 b5 1 | Db | 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.
