Eb13 chord

The E-flat dominant thirteenth chord (abbreviated Eb13 chord) is a seven-note chord consisting of the notes E♭, G, B♭, D♭, F, A♭, and C. The chord is formed by adding a thirteenth to the E-flat dominant eleventh chord.

In practice, the fifth (B♭) and eleventh (A♭) are often omitted from the Eb13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
