Guitar Chord Dictionary: D# Minor Major Seventh Chords
D#, F#, A# and C## spell the D#m(maj7) chord (D# minor major seventh). It sounds identical to Ebm(maj7), which uses Eb, Gb, Bb and a plain D.
The major seventh above D# is C##, a double sharp, which the flat spelling writes as a plain D. In either spelling the seventh lies a half step below the root. All four notes sit in the D# melodic minor scale. Flat-key charts show the same pitches as Eb, Gb, Bb and D, so the sound itself never changes. Both names describe the same pitches, so only the spelling differs.
D# minor major 7th guitar chord is also written as D#m(maj7), D#mM7, D#minmaj7 or D#-Δ7.
