Dbmaj13 chord
The D-flat major thirteenth chord (abbreviated "Dbmaj13 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 major eleventh chord.
In practice, the fifth (A♭) and eleventh (G♭) are often omitted from the Dbmaj13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
