— About this chord
G# dominant 7♭9 (1-3-5-♭7-♭9): a tense, chromatic dominant color built on the diminished-7-over-root shape, classic in jazz ii-V-i turnarounds and blues cadences. The compact movable grip (essentially a dim7 shape a major third above the root) resolves powerfully to C# major or minor. Also useful in bebop lines and tango harmony for a dark, urgent pull. Also searched as Ab7b9, G#dom7b9, A♭7♭9.
