Db7#11 — Db 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.

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 | 9-10-9-10-9-9 | Db G B F Ab Db | 1 #11 b7 3 5 1 | Db | 1 | 6 |
| 2 | 9-8-6-6-8-7 | Db F Ab Db G B | 1 3 5 1 #11 b7 | Db | 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.
