Bbm9 chord
The B-flat minor ninth chord (abbreviated "Bbm9 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 minor seventh chord.
In practice, the fifth (F) is sometimes omitted from the Bbm9 chord because it's not always possible to play all notes simultaneously.
