D# maj7 Chord
How the D# maj7 chord is built: its notes, its interval structure, and where it fits.
The D# maj7 chord contains 4 notes: D# – G – A# – D. It belongs to the seventh family of chord qualities. Like every chord, it is defined by the distances (intervals) between its notes, not by any one instrument — which is why the same formula names the chord whether it is voiced on a fretboard, a keyboard, or a choir.
