Explore the D#dim7 Guitar Chord in Musical Context

Need D diminished seventh rather than D#dim7? Jump to Ddim7.

The D# diminished seventh chord is usually written D#dim7 and uses the notes D#, F#, A and C. Every interval in the stack is a minor third, so no single note stands out as the obvious root. The page lists 11 voicings: 2 ring an open string and one is a barre shape.

It sounds identical to Ebdim7, the same pitches written with the other spelling. The E harmonic minor scale fits for a reason of harmony: in sound, D#dim7 is the vii chord of E harmonic minor, and every note belongs to that scale. Set a slow tempo with the drum tool at the top of the page and play along, raising the tempo once the shape feels settled.

D# diminished 7th guitar chord is also written as D#dim7, D#°7 or D#o7. It is also known as the D# fully diminished seventh chord.
