— About this chord
A#7b9 flattens the ninth against a dominant seventh, producing a sharp, unresolved tension that's a staple of jazz and Latin turnarounds, especially resolving down a fifth. The compact diminished-over-root shape is easy to slide chromatically for quick ii-V-i movement. Common in bebop heads and salsa montunos. Also searched as Bb7b9.
