A♭mmaj7♭5
A♭ Minor/Major 7th Flat 5 · 4 fingerings
A minor-major seventh with a flattened fifth, A♭mmaj7♭5 is one of the rarest chords in the book — the haunting quality of a minor-major with an extra layer of instability. It belongs to advanced jazz reharmonisation and modern composition. Worth knowing for the specific, very unsettled colour it provides.
