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
Scale (music) F# major. Through the introduction of blue notes, jazz and blues employ scale intervals smaller than a semitone. The blue note is an interval that is technically neither major nor minor but "in the middle", giving it a characteristic flavour. A regular piano cannot play blue notes, but with electric guitar, saxophone, trombone and trumpet, performers can "bend" notes a fraction of a tone sharp or flat to create blue notes For instance, in the key of E, the blue note would be either a note between G and G or a note moving between both. In blues, a pentatonic
