Dbm11 chord

The D-flat minor eleventh chord (abbreviated Dbm11 chord) is a six-note chord consisting of the notes D♭, F♭, A♭, C♭, E♭, and G♭. The chord is formed by adding an eleventh to the D-flat minor ninth chord.

In practice, the fifth (A♭) is often omitted from the Dbm11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
