Dbm9 chord

The D-flat minor ninth chord (abbreviated Dbm9 chord) is a five-note chord consisting of the notes D♭, F♭, A♭, C♭, and E♭. The chord is formed by adding a major ninth to the D-flat minor seventh chord.

In practice, the fifth (A♭) is sometimes omitted from the Dbm9 chord because it's not always possible to play all notes simultaneously.
