Fingering charts
The library holds 10 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# | 7 | Perfect fifth |
| 6 | E# | 9 | Major sixth |
| 9 | A# | 2 | Major second |
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# – E# – A# | 0 4 7 9 2 |
| first inversion | B# | 3 | B# – D# – E# – A# – G# | 0 3 5 10 8 |
| second inversion | D# | 5 | D# – E# – A# – G# – B# | 0 2 7 5 9 |
| third inversion | E# | 6 | E# – A# – G# – B# – D# | 0 5 3 7 10 |
| fourth inversion | A# | 9 | A# – G# – B# – D# – E# | 0 10 2 5 7 |
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 | 4-3-3-3-4-4 | G# C F A# D# G# | 1 3 6 9 5 1 | G# | 1 | 6 |
| 2 | 4-6-6-5-6-6 | G# D# G# C F A# | 1 5 1 3 6 9 | G# | 2 | 6 |
| 3 | 4-1-1-1-1-1 | G# A# D# G# C F | 1 9 5 1 3 6 | G# | 3 | 6 |
| 4 | 4-1-1-3-1-1 | G# A# D# A# C F | 1 9 5 9 3 6 | G# | 3 | 6 |
| 5 | 4-3-1-3-1-1 | G# C D# A# C F | 1 3 5 9 3 6 | G# | 3 | 6 |
| 6 | 4-3-1-3-4-1 | G# C D# A# D# F | 1 3 5 9 5 6 | 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.
