D# Aug Chord
How the D# Aug chord is built: its notes, its interval structure, and where it fits.
The D# Aug chord contains 3 notes: D# – G – B. It belongs to the diminished & augmented 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.
