A#7#11 — A# dominant seventh sharp eleventh chord
A dominant seventh chord with the eleventh raised. The sharp eleventh is a tritone above the root, which is why the chord is stable enough to hold: the usual clash between the third and the eleventh is gone.

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 | A# | 0 | Perfect unison |

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 | A# | 1 | A# – C## – E# – G# – D## | 0 4 7 10 6 |
| first inversion | C## | 3 | C## – E# – G# – D## – A# | 0 3 6 2 8 |
| second inversion | E# | 5 | E# – G# – D## – A# – C## | 0 3 11 5 9 |
| third inversion | G# | b7 | G# – D## – A# – C## – E# | 0 8 2 6 9 |
| fourth inversion | D## | #11 | D## – A# – C## – E# – G# | 0 6 10 1 4 |
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 | 6-7-6-7-6-6 | A# E G# D F A# | 1 #11 b7 3 5 1 | A# | 1 | 6 |
| 2 | 6-5-3-3-5-4 | A# D F A# E G# | 1 3 5 1 #11 b7 | A# | 3 | 6 |
| 3 | 6-7-6-7-6-4 | A# E G# D F G# | 1 #11 b7 3 5 b7 | A# | 3 | 6 |
| 4 | 6-8-6-7-5-6 | A# F G# D E A# | 1 5 b7 3 #11 1 | A# | 3 | 6 |
| 5 | 6-5-2-3-6-4 | A# D E A# F G# | 1 3 #11 1 5 b7 | A# | 4 | 6 |
| 6 | 6-7-3-3-3-4 | A# E F A# D G# | 1 #11 5 1 3 b7 | A# | 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.
