B11 chord
The B dominant eleventh chord (abbreviated "B11 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 a B dominant ninth chord.
In practice, the third (D♯) and fifth (F♯) are often omitted from the B11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
