How it is built

Ab13 is the fullest dominant extension, adding a 13th on top of the 9th and seventh. In practice the 11th is usually omitted (it clashes with the 3rd), leaving root, 3rd, 7th, 9th, and 13th as the essential tones.

Common musical function

Dominant 13 chords are a jazz staple for the V chord, offering the richest common dominant color before resolving to the tonic.
