Abmaj11 chord
The A-flat major eleventh chord (abbreviated "Abmaj11 chord") is a six-note chord consisting of the notes A♭, C, E♭, G, B♭, and D♭. The chord is formed by adding an eleventh to a A-flat major ninth chord.
In practice, the fifth (E♭) is often omitted from the Abmaj11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
