The B-sharp minor ninth chord (abbreviated B#m9 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-sharp minor seventh chord.

In practice, the fifth (F) is sometimes omitted from the B#m9 chord because it's not always possible to play all notes simultaneously.
