The A-flat major ninth chord (abbreviated Abmaj9 chord) is a five-note chord consisting of the notes A, C, E, G, and B. The chord is formed by adding a major ninth to the A-flat major seventh chord.

In practice, the fifth (E) is sometimes omitted from the Abmaj9 chord because it's not always possible to play all notes simultaneously.
