'''C-sharp major''' is a [[major scale]] based on [[C♯ (musical note)|C{{music|sharp}}]], consisting of the pitches C{{music|sharp}}, [[D♯ (musical note)|D{{music|sharp}}]], [[E♯ (musical note)|E{{music|sharp}}]], [[F♯ (musical note)|F{{music|sharp}}]], [[G♯ (musical note)|G{{music|sharp}}]], [[A♯ (musical note)|A{{music|sharp}}]], and [[C (musical note)|B{{music|sharp}}]]. Its [[key signature]] has seven [[Sharp (music)|sharps]]. Its [[relative key|relative minor]] is [[A-sharp minor]] (or [[Enharmonic|enharmonically]] [[B-flat minor]]), its [[parallel key|parallel minor]] is [[C-sharp minor]], and its [[enharmonic equivalence|enharmonic equivalent]] is [[D-flat major]].
 
The C-sharp major scale is:
 
:{{block indent|<score sound="1"> {raw>
\header { tagline = ##f }
\omit Score.TimeSignature \relative c' {
scale = \relative b { \key cis \major \omit Score.TimeSignature
\key cis \major \time 7/4 cis dis eis fis gis ais bis cis bis ais gis fis eis dis cis2
cis^"C♯ natural major scale" dis eis fis gis ais bis cis bis ais gis fis eis dis cis2 \clef F \key cis \major }
\score { { << \cadenzaOn \scale \context NoteNames \scale >> } \layout { } \midi { } }
} }
</score>}}
 
Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The C-sharp [[Harmonic major scale|harmonic major]] and [[Melodic major scale|melodic major scales]] are:
 
{{block indent|<score sound raw>
\header { tagline = ##f }
scale = \relative b { \key cis \major \omit Score.TimeSignature
\key cis^"C♯ harmonic \major \time 7/4 cisscale" dis eis fis gis aisa bis cis bis aisa gis fis eis dis cis2 }
\score { { << \cadenzaOn \scale \context NoteNames \scale >> } \layout { } \midi { } }
</score>}}
{{block indent|<score sound raw>
\header { tagline = ##f }
scale = \relative b { \key cis \major \omit Score.TimeSignature
cis^"C♯ melodic major scale (ascending and descending)" dis eis fis gis ais bis cis b a gis fis eis dis cis2 }
\score { { << \cadenzaOn \scale \context NoteNames \scale >> } \layout { } \midi { } }
</score>}}
 
A [[harp]] tuned to C-sharp major has all its pedals in the bottom position. Because all the strings are then pinched and shortened, this is the least resonant key for the instrument.

== Scale degree chords ==
The [[scale degree]] chords of C-sharp major are:
* '''[[Tonic (music)|Tonic]]''' – C-sharp major
* '''[[Supertonic]]''' – [[D-sharp minor]]
* '''[[Mediant]]''' – [[E-sharp minor]]
* '''[[Subdominant]]''' – [[F-sharp major]]
* '''[[Dominant (music)|Dominant]]''' – [[G-sharp major]]
* '''[[Submediant]]''' – [[A-sharp minor]]
* '''[[Leading-tone]]''' – [[Diminished triad|B-sharp diminished]]
 
==Compositions==
Most composers prefer to use the [[enharmonic]] equivalent [[D-flat major]] since it contains five flats as opposed to C-sharp major's seven sharps. However, [[Johann Sebastian Bach]] chose C-sharp major for Prelude and Fugue No. 3 in both books of ''[[The Well-Tempered Clavier]]''. In [[Hungarian Rhapsody No. 6]], [[Franz Liszt]] takes the unusual step of changing the key from [[D-flat major]] to C-sharp major near the start of the piece, and then back again to B-flat minor. [[Maurice Ravel]] selected C-sharp major as the tonic key of "Ondine" from his piano suite ''[[Gaspard de la nuit]]''. [[Erich Wolfgang Korngold]] composed his [[Piano Concerto for the Left Hand (Korngold)|Piano Concerto for the Left Hand]], Op. 17, in C-sharp major.
 
The ''[[Allegro de concierto]]'' by Spanish composer [[Enrique Granados]] is written in C-sharp major. Canadian composer and pianist [[Frank Mills]] originally wrote and performed his instrumental hit "[[Music Box Dancer]]" in C-sharp major; however, most modern piano editions have the piece written in [[C major]].
 
[[Louis Vierne]] used C-sharp major for the "Dona nobis pacem" of the Agnus Dei of his ''[[Messe solennelle (Vierne)|Messe solennelle]]'' in [[C-sharp minor]].
