— About this chord
G# dominant 7♭5 (1-3-♭5-♭7): a whole-tone/Lydian-dominant flavored chord with a lowered 5th, giving dominant harmony an unstable, floating quality prized in jazz-fusion and modern blues reharmonization. Frequently substitutes for a plain dominant 7 in tritone-substitution contexts. The A-position grip anchors the root on the 5th string, with mid and low-neck alternatives for smoother voice leading. Also searched as Ab7b5, G#dom7b5, A♭7♭5.
