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 and is now playing in B major, marked with the necessary sharps and naturals as accidentals. This use of C major in harp parts when the rest of the orchestra is playing in B major is not exceptional: it is standard practice in orchestral music written in B major for harp parts to be notated in C major. In Arnold Bax's symphonic poem "Tintagel", the key is B major and again the harp part is always notated in C major; but in this case the harp's key signature contains only 6 flats, and the necessary Fs are notated with accidentals.
