Its relative major is C-sharp major (or enharmonically D-flat major). Its parallel major, A-sharp major, is usually replaced by B-flat major, since A-sharp major's three double-sharps make it impractical to use. The direct enharmonic equivalent of A-sharp minor is B-flat minor, which only contains five flats and is often preferable to use.


The A-sharp natural minor scale is:

{ \override Score.TimeSignature #'stencil = ##f \relative c'' { \clef treble \key ais \minor \time 7/4 ais4^\markup "Natural minor scale" bis cis dis eis fis gis ais gis fis eis dis cis bis ais2 \clef bass \key ais \minor } }

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

{ \override Score.TimeSignature #'stencil = ##f \relative c'' { \clef treble \key ais \minor \time 7/4 ais4^\markup "Harmonic minor scale" bis cis dis eis fis gisis ais gisis fis eis dis cis bis ais2 } }
{ \override Score.TimeSignature #'stencil = ##f \relative c'' { \clef treble \key ais \minor \time 7/4 ais4^\markup "Melodic minor scale (ascending and descending)" bis cis dis eis fisis gisis ais gis! fis! eis dis cis bis ais2 } }

In Christian Heinrich Rinck's 30 Preludes and Exercises in all major and minor keys, Op. 67, the 16th Prelude and Exercise is in A-sharp minor. In Bach's Prelude and Fugue in C-sharp major, BWV 848, a brief section near the beginning of the piece modulates to A-sharp minor.
