Gm7b5

About this chord

Gm7b5 (G half-diminished, Gø7) has a smoky, tense, melancholic color—mysterious, bittersweet, and suspenseful. A staple of jazz and blues minor harmony and common in film-score noir cues, it also appears in classical and Latin ballads. Its flavor can hint at Mediterranean or tango moods, adding a dusky, dramatic flair. Technically a sophisticated voicing, often played as a closed or barre shape, it rewards careful voice-leading. Frequently used as iiø7 in minor keys, it builds unresolved tension that resolves to V or i, ideal for moody turnarounds and late-night progressions.
