D#13 chord
The D-sharp dominant thirteenth chord (abbreviated "D#13 chord") is a seven-note chord consisting of the notes D♯, F, A♯, C♯, E♯, G♯, and B♯. The chord is formed by adding a thirteenth to a D-sharp dominant eleventh chord.
In practice, the fifth (A♯) and eleventh (G♯) are often omitted from the D#13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
