Dmaj11 chord

The D major eleventh chord (abbreviated Dmaj11 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 the D major ninth chord.

In practice, the fifth (A) is often omitted from the Dmaj11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
