F♯ Altered
F♯ · G · G♯♯ · A♯ · B♯ · D · E
Also called Super Locrian, F♯ Altered is the seventh mode of melodic minor and contains every altered extension a dominant chord can take — flat and sharp ninth, flat and sharp fifth. It's the definitive jazz scale for a V chord that needs maximum tension before resolving. Learn it as melodic minor a semitone up from the root.
