D♭sus4 (D♭sus4)

Also called C♯sus4 (C♯sus4).

The third is replaced by the fourth, so the chord is neither major nor minor. The fourth usually pulls back toward the major chord.

There’s no open shape: it’s played as a barre chord, starting at the 4th fret. It’s mostly used to add movement to D♭ major, which it resolves to.
