How to use the A13 chord
The A13 chord is built from a root, a major third, a minor seventh, a major ninth and a major thirteenth. Start at the root A and stack the intervals to get the whole chord: A, C♯, G, B and F♯. The same formula gives you the chord in any other key.
Dominant thirteenth chords are the default rich dominant in jazz, gospel and R&B horn and keyboard voicings, usually the V7 resolving to a major or minor tonic. Big band charts lean on them wherever a plain dominant seventh would sound thin.
Where A13 is used
