G-flat major is a major scale based on G-flat, consisting of the pitches G♭, A♭, B♭, C♭, D♭, E♭, and F. Its key signature has six flats.
Its relative minor is E♭ minor (or enharmonically D♯ minor) and its parallel minor is G♭ minor, usually replaced by F♯ minor, since G♭ minor's two double-flats make it generally impractical to use.
The direct enharmonic equivalent of G♭ major is F♯ major, a key signature with six sharps.
