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 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.

Like F major, G major is rarely chosen as the main key for orchestral works, it is more often used as a main key for piano works, such as the impromptus of Chopin and Schubert. It is the predominant key of Maurice Ravel's Introduction and Allegro for harp, flute, clarinet and string quartet.
