Bmaj11 chord

The B major eleventh chord (abbreviated Bmaj11 chord) is a six-note chord consisting of the notes B, D♯, F♯, A♯, C♯, and E. The chord is formed by adding an eleventh to the B major ninth chord.

In practice, the fifth (F♯) is often omitted from the Bmaj11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
