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.

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.
