D#maj13 chord

The D-sharp major thirteenth chord (abbreviated D#maj13 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 the D-sharp major eleventh chord.

In practice, the fifth (A♯) and eleventh (G♯) are often omitted from the D#maj13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
