D#m(maj7) — D# minor major seventh chord
A minor triad with a major seventh added. The interval between the minor third and the major seventh is a major third and the interval between the seventh and the root is a semitone, so the chord is unstable.

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 | D# | 0 | Perfect unison |
| b3 | F# | 3 | Minor third |
| 5 | A# | 7 | Perfect fifth |
| 7 | C## | 11 | Major seventh |
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 | D# | 1 | D# – F# – A# – C## | 0 3 7 11 |
| first inversion | F# | b3 | F# – A# – C## – D# | 0 4 8 9 |
| second inversion | A# | 5 | A# – C## – D# – F# | 0 4 5 8 |
| third inversion | C## | 7 | C## – D# – F# – A# | 0 1 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 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.
