How it is built
On Db the complete chord is Db · F · Ab · Cb · Eb · Bb, stacking 1P · 3M · 5P · 7m · 9M · 13M. Seven notes is more than any keyboard voicing wants and more than most ensembles can state clearly.
How it is used
What players actually voice is root, third, seventh and thirteenth — the notes that carry the identity. The fifth goes first, the eleventh next, and the ninth is optional.
It is the standard big-band dominant: full, bright, and still resolving, because the tritone between third and seventh is untouched.
