C-sharp minor is a minor scale based on C, with the pitches C, D, E, F, G, A, and B. Its key signature consists of four sharps.

The C-sharp natural minor scale is:

 {
\omit Score.TimeSignature \relative c' {
  \key cis \minor \time 7/4 cis^"Natural minor scale" dis e fis gis a b cis b a gis fis e dis cis2
  \clef F \key cis \minor
} }

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The C-sharp harmonic minor and melodic minor scales are:

 {
\omit Score.TimeSignature \relative c' {
  \key cis \minor \time 7/4 cis^"Harmonic minor scale" dis e fis gis a bis cis bis a gis fis e dis cis2
} }
 {
\omit Score.TimeSignature \relative c' {
  \key cis \minor \time 7/4 cis^"Melodic minor scale (ascending and descending)" dis e fis gis ais bis cis b? a? gis fis e dis cis2
} }

Its relative major is E major. Its parallel major, C-sharp major, is usually written instead as the enharmonic key of D-flat major, since C-sharp major’s key signature with seven sharps is not normally used. Its enharmonic equivalent, D-flat minor, having eight flats including the Bdouble flat, has a similar problem. Therefore, C-sharp minor is often used as the parallel minor for D-flat major. (The same enharmonic situation occurs with the keys of A-flat major and G-sharp minor, and in some cases, with the keys of G-flat major and F-sharp minor.)
