E#13 chord

The E-sharp dominant thirteenth chord (abbreviated E#13 chord) is a seven-note chord consisting of the notes E♯, G𝄪, B♯, D♯, F𝄪, A♯, and C𝄪. The chord is formed by adding a thirteenth to the E-sharp dominant eleventh chord.

In practice, the fifth (B♯) and eleventh (A♯) are often omitted from the E#13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
