A7(b9) chord
The A dominant minor ninth chord (abbreviated A7(b9) chord) is a five-note chord consisting of the notes A, C♯, E, G, and B♭. The chord is formed by adding a minor ninth to the A dominant seventh chord.
In practice, the fifth (E) is often omitted from the A7(b9) chord because it's not always possible to play all notes simultaneously.
