F-flat major F-flat major F major (or the key of F) is a theoretical key based on F, consisting of the pitches F, G, A, B, C, D, and E Its key signature has six flats and one double flat. The F major scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> Its relative minor is D minor, usually replaced by C minor (see reason below) and its parallel minor is F minor, usually replaced by E minor, since F minor's four double-flats make it generally impractical to use. Because of that, it is usually enharmonic to E major with
G-flat major and Winding used G-flat major over F-sharp major, but this does not affect the integrity of the scheme as the key sequence breaks down. Muzio Clementi chose G-flat for the "Grande Exercice" and F-sharp for the prelude. Antonín Dvořák composed Humoresque No. 7 in G-flat major, while its middle section is F-sharp minor. Gustav Mahler was fond of using G-flat major in key passages of his symphonies.
