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
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.
