Its key signature has seven sharps. Its relative minor is A-sharp minor (or enharmonically B-flat minor), its parallel minor is C-sharp minor, and its enharmonic equivalent is D-flat major.
The C-sharp major scale is:
\header { tagline = ##f } scale = \relative b { \key cis \major \omit Score.TimeSignature 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 { { } \layout { } \midi { } }
Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The C-sharp harmonic major and melodic major scales are:
\header { tagline = ##f } scale = \relative b { \key cis \major \omit Score.TimeSignature cis^"C♯ harmonic major scale" dis eis fis gis a bis cis bis a gis fis eis dis cis2 } \score { { } \layout { } \midi { } } \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 { { } \layout { } \midi { } }
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 – C-sharp major
- Supertonic – D-sharp minor
- Mediant – E-sharp minor
- Subdominant – F-sharp major
- Dominant – G-sharp major
- Submediant – A-sharp minor
- Leading-tone – 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, 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 in C-sharp minor.
