Ebm11 chord

The E-flat minor eleventh chord (abbreviated Ebm11 chord) is a six-note chord consisting of the notes E♭, G♭, B♭, D♭, F, and A♭. The chord is formed by adding an eleventh to the E-flat minor ninth chord.

In practice, the fifth (B♭) is often omitted from the Ebm11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
