Eb9 chord

The E-flat dominant ninth chord (abbreviated Eb9 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 the E-flat dominant seventh chord.

In practice, the fifth (B♭) is sometimes omitted from the Eb9 chord because it's not always possible to play all notes simultaneously.
