How to use the B♯13 chord
The B♯13 chord is built from a root, a major third, a minor seventh, a major ninth and a major thirteenth. Start at the root B♯ and stack the intervals to get the whole chord: B♯, D𝄪, A♯, C𝄪 and G𝄪. 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 B♯13 is used
A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.
