Fingering charts
The library holds 2 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 |
| 3 | B♭ | 4 | Major third |
| #5 | D | 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 | G♭ | 1 | G♭ – B♭ – D | 0 4 8 |
| first inversion | B♭ | 3 | B♭ – D – G♭ | 0 4 8 |
| second inversion | D | #5 | D – G♭ – B♭ | 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 | 2-1-0-3-3-2 | Gb Bb D Bb D Gb | 1 3 #5 3 #5 1 | Gb | 3 | 6 |
| 2 | 2-1-4-3-3-2 | Gb Bb Gb Bb D Gb | 1 3 1 3 #5 1 | Gb | 3 | 6 |
| 3 | 2-5-4-3-3-2 | Gb D Gb Bb D Gb | 1 #5 1 3 #5 1 | Gb | 3 | 6 |
| 4 | 14-13-12-11-11-14 | Gb Bb D Gb Bb Gb | 1 3 #5 1 3 1 | Gb | 3 | 6 |
| 5 | 14-13-12-15-15-14 | Gb Bb D Bb D Gb | 1 3 #5 3 #5 1 | Gb | 3 | 6 |
| 6 | 2-5-4-3-3-6 | Gb D Gb Bb D Bb | 1 #5 1 3 #5 3 | 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.
