Bbmaj9 chord
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 a 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.
