D7(#9) chord
The D dominant seventh sharp ninth chord (abbreviated "D7(#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 dominant seventh chord.
In practice, the fifth (A) is often omitted from the D7(#9) chord because it's not always possible to play all notes simultaneously.
