D-flat minor is a

enharmonic equivalent, C-sharp minor
, is normally used.

The D-flat

natural minor scale
is:

{ \omit Score.TimeSignature \relative c' { \key des \minor \time 7/4 des^"Natural minor scale" es fes ges aes beses ces des ces beses aes ges fes es des2 \clef F \key des \minor } }

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The D-flat

melodic minor scales
are:

{ \omit Score.TimeSignature \relative c' { \key des \minor \time 7/4 des^"Harmonic minor scale" es fes ges aes beses c des c beses aes ges fes es des2 } }
{ \omit Score.TimeSignature \relative c' { \accidentalStyle modern \key des \minor \time 7/4 des^"Melodic minor scale" es fes ges aes bes c des ces? beses? aes ges fes es des2 } }

D-flat minor is usually notated as the enharmonic key of C-sharp minor, as in the second and third measures of Amy Beach's Canticle of the Sun.[1] However, unusually, two of Verdi's most well-known operas, La traviata and Rigoletto, both end in D-flat minor (although written with the five-flat key signature of the parallel major). Mahler's thematic motif "der kleine Appell" ("call to order") from his Fourth and Fifth Symphonies uses both notations: in his Symphony No. 4 (first movement) it is in D-flat minor, but in his Symphony No. 5 it is in C-sharp minor. In the Adagio of his Symphony No. 9, a solo bassoon interpolation following the main theme appears first in D-flat minor, returning twice more notated in C-sharp minor. Likewise, in the Adagio of Bruckner's Symphony No. 8, phrases that are tonally in D-flat minor are notated as C-sharp minor.[2][3][4][5]

D-flat minor key signatures are used on Max Reger's On the Theory of Modulation on pp. 42–45.[6]
