Dbm13 chord
The D-flat minor thirteenth chord (abbreviated "Dbm13 chord") is a seven-note chord consisting of the notes D♭, F♭, A♭, C♭, E♭, G♭, and B♭. The chord is formed by adding a thirteenth to a D-flat minor eleventh chord.
In practice, the fifth (A♭) and eleventh (G♭) are often omitted from the Dbm13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
