B9 chord
The B dominant ninth chord (abbreviated B9 chord) is a five-note chord consisting of the notes B, D♯, F♯, A, and C♯. The chord is formed by adding a major ninth to the B dominant seventh chord.
In practice, the fifth (F♯) is sometimes omitted from the B9 chord because it's not always possible to play all notes simultaneously.
