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
C-flat major major, although they usually notate this with accidentals in some other key signature, seldom a 7-flat key signature: for example: C major is used for Benjamin Britten's "Interlude" in C major for harp, several of Max Reger's Canons in All Major and Minor Keys (Book 1 Nos. 62 and 63, and Book 2 No. 48), and No. 29 from the "Thirty Preludes in All Major and Minor Keys" by Christian Heinrich Rinck.
