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
B-flat major and dominant pitches. Many editions of the work, however, use no key signature and specify the instrument as "Timpani in B–F". Five of Mozart's piano concertos are in B-flat major. B-flat major In music theory, B-flat major is a major scale based on B, with pitches B, C, D, E, F, G, and A. Its key signature has two flats. Its relative minor is G minor and its parallel minor is B-flat minor. The B-flat major scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> Many transposing instruments are pitched in B-flat major, including the clarinet, trumpet, tenor
