D♯dim7

D♯1F♯♭3A♭5C♭♭7

Three minor thirds stacked. The seventh is doubly diminished, which is why it is written with a double flat.

Written the other way round it is E♭dim7 — the same twelve keys on a piano, a different piece of notation.

What is true of it

D♯dim7 is D♯, F♯, A and C — 1, b3, b5 and bb7 counted from D♯.

The easiest of the 5 fingerings below is xx1212: 3 fingers, one of them barring the 1st fret, held at the 1st fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

3 of the 5 need a barre.

2 strings stay silent.

The brass dots are D♯, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
