G-sharp minor is a minor scale based on G♯, consisting of the pitches G♯, A♯, B, C♯, D♯, E, and F♯. For the harmonic minor, the F♯ is raised to F (enharmonic G♮). Its key signature has five sharps.
 (enharmonic G♮). Its key signature has five sharps.
Its relative major is B major. Its parallel major, G♯ major, is usually replaced by its enharmonic equivalent of A♭ major, since G♯ major features an F in the key signature and A♭ major only has four flats, making it rare for G♯ major to be used. A♭ minor, with seven flats, has a similar problem, thus G♯ minor is often used as the parallel minor for A♭ major. The same enharmonic situation occurs with the keys of D♭ major and C♯ minor, with C♯ major having seven sharps and D♭ minor having eight flats, including the B
