D#m9 chord
The D-sharp minor ninth chord (abbreviated "D#m9 chord") is a five-note chord consisting of the notes D♯, F♯, A♯, C♯, and E♯. The chord is formed by adding a major ninth to a D-sharp minor seventh chord.
In practice, the fifth (A♯) is sometimes omitted from the D#m9 chord because it's not always possible to play all notes simultaneously.
