The B-flat dominant seventh sharp ninth chord (abbreviated Bb7(#9) chord) is a five-note chord consisting of the notes B, D, F, A, and C. The chord is formed by adding an augmented ninth to the B-flat dominant seventh chord.

In practice, the fifth (F) is often omitted from the Bb7(#9) chord because it's not always possible to play all notes simultaneously.
