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 the 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.
