E#9 chord
The E-sharp dominant ninth chord (abbreviated "E#9 chord") is a five-note chord consisting of the notes E♯, G, B♯, D♯, and F. The chord is formed by adding a major ninth to a E-sharp dominant seventh chord.
In practice, the fifth (B♯) is sometimes omitted from the E#9 chord because it's not always possible to play all notes simultaneously.
