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
A-flat major as flatter major keys were notated as their enharmonic equivalents. Felix Mendelssohn, Johann Nepomuk Hummel, John Field, and Friedrich Kalkbrenner each wrote one piano concerto in A-flat (Mendelssohn's being for two pianos); they had the horns and trumpet tuned to E-flat. Max Bruch's Concerto for Two Pianos in A-flat minor has its last movement in A-flat major, which is the parallel major; this concerto plays with the contrast between the two keys. Other compositions in A-flat major include: A-flat major A-flat major (or the key of A-flat) is a major scale based on A, with the pitches A, B, C,
