A♭ suspended 4th chord

Playing it

There’s no open-string way to play A♭sus4 on guitar with the root in the bass, so the standard shape is a barre across the 4th fret (446644). While you build strength, you can play just the top four strings of the same shape (xx6644).

On piano, every note of A♭sus4 is a black key.

On ukulele the usual A♭sus4 shape is 1344, using four fingers.
