The B-flat major ninth chord (abbreviated Bbmaj9 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-flat major seventh chord.

In practice, the fifth (F) is sometimes omitted from the Bbmaj9 chord because it's not always possible to play all notes simultaneously.
