B#maj13 chord
The B-sharp major thirteenth chord (abbreviated "B#maj13 chord") is a seven-note chord consisting of the notes B♯, D, F, A, C, E♯, and G. The chord is formed by adding a thirteenth to a B-sharp major eleventh chord.
In practice, the fifth (F) and eleventh (E♯) are often omitted from the B#maj13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
