A#maj11 chord
The A-sharp major eleventh chord (abbreviated "A#maj11 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-sharp major ninth chord.
In practice, the fifth (E♯) is often omitted from the A#maj11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
