Ascending and descending G-flat Major Scale

Its relative minor is E flat minor, and its parallel minor is G flat minor, usually replaced by F sharp minor, since G flat minor, which would have nine flats, is not normally used. Its enharmonic equivalent is F sharp major, whose key signature has as many sharps as G flat major has flats. In writing music in E major for B flat instruments, it is preferable to use a G flat rather an F sharp key signature.

Hardly chosen as the main key for orchestral works, G flat major is more often used as a main key for piano works, such as the impromptus of Chopin and Schubert.

Austrian composer Gustav Mahler was fond of using G flat major in key passages of his symphonies; examples include: The choral entry during the finale of his Second Symphony,[1] during the first movement of his Third Symphony,[2] the modulatory section of the Adagietto from his Fifth Symphony,[3] and during the Rondo-Finale of his Seventh Symphony.[4] Mahler's Tenth Symphony was composed in the enharmonic key of F sharp major.
