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.

Scale (music) scale is often used. In jazz, many different modes and scales are used, often within the same piece of music. Chromatic scales are common, especially in modern jazz. In Western music, scale notes are often separated by Equal temperament tones or semitones, creating 12 intervals per octave each separating two tones where the higher tone has a oscillation frequency of a fixed ratio (by a factor equal to the twelfth root of two, or approximately 1.059463) higher than the frequency of the lower one. A scale uses a subset consisting typically of 7 of these 12 as scale steps. Other
