G major (or the key of G) is a theoretical key based on the musical note G, consisting of the pitches G, A, B, C, D, E and Fdouble sharp. Its key signature has six sharps and one double sharp.[1]

Its relative minor is E minor (usually replaced by F minor), its parallel minor is G minor, and its enharmonic equivalent is A major.

The G♯ major scale is:

Although G major is usually notated as the enharmonic key of A major, because A major has only four flats as opposed to G major's eight sharps (including the Fdouble sharp), it does appear as a secondary key area in several works in sharp keys, most notably in the Prelude and Fugue in C major from Johann Sebastian Bach's The Well-Tempered Clavier, Book 1. The G minor prelude (and, in some editions, the fugue) from the same set ends with a Picardy third, on a G major chord.

G major is tonicised briefly in several of Frédéric Chopin's nocturnes in C minor. A section in the second movement of Chopin's Piano Concerto No. 1 is in G major, although the key signature has four sharps. The end of the exposition of the second movement Charles-Valentin Alkan's Grande sonate 'Les quatre âges', subtitled Quasi-Faust, is in G major, albeit written with a six-sharp key signature (the movement opens in D minor and ends in F major).

The final pages of A World Requiem by John Foulds are written in G major with its correct key signature shown in the vocal score including the Fdouble sharp.[2]
