Eb7(b9) chord
The E-flat dominant minor ninth chord (abbreviated "Eb7(b9) chord") is a five-note chord consisting of the notes E♭, G, B♭, D♭, and F♭. The chord is formed by adding a major ninth to a E-flat dominant seventh chord.
In practice, the fifth (B♭) is often omitted from the Eb7(b9) chord because it's not always possible to play all notes simultaneously.
