D#11 chord
The D-sharp dominant eleventh chord (abbreviated "D#11 chord") is a six-note chord consisting of the notes D♯, F, A♯, C♯, E♯, and G♯. The chord is formed by adding an eleventh to a D-sharp dominant ninth chord.
In practice, the third (F) and fifth (A♯) are often omitted from the D#11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
