— About this chord

G7b5 (1-3-b5-b7) flats the 5th of a dominant chord for a whole-tone, off-kilter tension — smoother and more ambiguous than the #5 version, often used as a passing or substitute dominant in jazz reharmonization. Frequently appears in tritone-substitution contexts and Monk-style comping, adding an unresolved, floating color before resolving down a step or a fifth. Also searched as G7-5, G7 flat 5.
