The D-flat dominant thirteenth chord (abbreviated "Db13 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 dominant eleventh chord.

In practice, the fifth (A) and eleventh (G) are often omitted from the Db13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
