E#11 chord

The E-sharp dominant eleventh chord (abbreviated E#11 chord) is a six-note chord consisting of the notes E♯, G, B♯, D♯, F, and A♯. The chord is formed by adding an eleventh to the E-sharp dominant ninth chord.

In practice, the third (G) and fifth (B♯) are often omitted from the E#11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
