D#7(#9) chord
The D-sharp dominant seventh sharp ninth chord (abbreviated "D#7(#9) chord") is a five-note chord consisting of the notes D♯, F, A♯, C♯, and E. The chord is formed by adding an augmented ninth to a D-sharp dominant seventh chord.
In practice, the fifth (A♯) is often omitted from the D#7(#9) chord because it's not always possible to play all notes simultaneously.
