Bb7(b9) chord
The B-flat dominant minor ninth chord (abbreviated Bb7(b9) chord) is a five-note chord consisting of the notes B♭, D, F, A♭, and C♭. The chord is formed by adding a minor ninth to the B-flat dominant seventh chord.
In practice, the fifth (F) is often omitted from the Bb7(b9) chord because it's not always possible to play all notes simultaneously.
