The E-sharp dominant seventh sharp ninth chord (abbreviated "E#7(#9) chord") is a five-note chord consisting of the notes E, G, B, D, and F. The chord is formed by adding an augmented ninth to a E-sharp dominant seventh chord.

In practice, the fifth (B) is often omitted from the E#7(#9) chord because it's not always possible to play all notes simultaneously.
