Fingering charts
The library holds 4 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.

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# – A# – B – D# – F# | 0 2 3 7 10 |
| first inversion | A# | 9 | A# – B – D# – F# – G# | 0 1 5 8 10 |

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 | 4-2-4-3-4-2 | G# B F# A# D# F# | 1 b3 b7 9 5 b7 | G# | 2 | 6 |
| 2 | 4-2-4-3-4-4 | G# B F# A# D# G# | 1 b3 b7 9 5 1 | G# | 2 | 6 |
| 3 | 4-6-4-4-4-6 | G# D# F# B D# A# | 1 5 b7 b3 5 9 | G# | 2 | 6 |
| 4 | 4-1-1-4-4-2 | G# A# D# B D# F# | 1 9 5 b3 5 b7 | G# | 3 | 6 |
| 5 | 4-2-1-3-4-2 | G# B D# A# D# F# | 1 b3 5 9 5 b7 | G# | 3 | 6 |
| 6 | 4-1-4-4-4-2 | G# A# F# B D# F# | 1 9 b7 b3 5 b7 | G# | 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.
