A♭sus4 (A♭sus4)

Also called G♯sus4 (G♯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 A♭ major, which it resolves to.
