G-sharp major

G-sharp major is a major scale based on the musical note G sharp. Its key signature has eight sharps.

To make reading easier, G-sharp major is usually written as its enharmonic equivalent of A-flat major. However, it does appear as a secondary key area in several works in sharp keys, for example in the Prelude and Fugue in C sharp major from Bach's Well-Tempered Klavier, Book 1. The G sharp minor Prelude and Fugue from the same set end with a Picardy third in G sharp major. 
G sharp major is used for a short time in several of Chopin's nocturnes in C sharp minor.
