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 | G♭ | 0 | Perfect unison |
| b3 | B♭♭ | 3 | Minor third |
| 5 | D♭ | 7 | Perfect fifth |
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 | G♭ | 1 | G♭ – B♭♭ – D♭ | 0 3 7 |
| first inversion | B♭♭ | b3 | B♭♭ – D♭ – G♭ | 0 4 9 |
| second inversion | D♭ | 5 | D♭ – G♭ – B♭♭ | 0 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 | 2-4-4-2-2-2 | Gb Db Gb A Db Gb | 1 5 1 b3 5 1 | Gb | 2 | 6 |
| 2 | 2-4-4-2-2-5 | Gb Db Gb A Db A | 1 5 1 b3 5 b3 | Gb | 3 | 6 |
| 3 | 14-12-11-11-14-14 | Gb A Db Gb Db Gb | 1 b3 5 1 5 1 | Gb | 3 | 6 |

| 5 | 2-0-4-2-2-2 | Gb A Gb A Db Gb | 1 b3 1 b3 5 1 | Gb | 4 | 6 |
| 6 | 2-4-4-6-2-5 | Gb Db Gb Db Db A | 1 5 1 5 5 b3 | Gb | 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.
