D-flat minor D-flat minor D minor is a theoretical key based on D, consisting of the pitches D, E, F, G, A, B, and C. Its key signature has six flats and one double flat. Its relative major is F major (usually replaced by E major), its parallel major is D major, its direct enharmonic equivalent is C♯ minor, which is normally used. The D natural minor scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The D harmonic minor and melodic
D-flat major its enharmonic, with seven sharps, has a similar problem. Therefore, D-flat major is often used as the parallel major for C-sharp minor. (The same enharmonic situation occurs with the keys of A-flat major and G-sharp minor). For example, in his Prelude No. 15 in D-flat major ("Raindrop"), Frédéric Chopin switches from D-flat major to C-sharp minor for the middle section in the parallel minor, while in his "Fantaisie-Impromptu" and Scherzo No. 3, primarily in C-sharp minor, he switches to D-flat major for the middle section for the opposite reason. Ferdinand Ries' third concerto likewise switches to D-flat major for a
