G-sharp major

Tonality

G-sharp major is a musical key based on G♯, consisting of the pitches G♯, A♯, B♯, C♯, D♯, E♯, and F. Its key signature has eight sharps, requiring one double sharp and six single sharps. Because the same pitches can be indicated by the enharmonically equivalent key of A-flat major (with four flats), a G-sharp major key signature is extremely rare.
