A-sharp minor is a minor musical scale based on A, consisting of the pitches A, B, C, D, E, F, and G. Its key signature has seven sharps.[1]

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.[citation needed] The enharmonic equivalent of A-sharp minor is B-flat minor,[1] which only contains five flats and is often preferable to use.[citation needed]

The A-sharp natural minor scale is:

\omit Score.TimeSignature \relative c'' {
  \key ais \minor \time 7/4 ais^"Natural minor scale" bis cis dis eis fis gis ais gis fis eis dis cis bis ais2 \clef F \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:

\omit Score.TimeSignature \relative c'' {
  \key ais \minor \time 7/4 ais^"Harmonic minor scale" bis cis dis eis fis gisis ais gisis fis eis dis cis bis ais2
} }
\omit Score.TimeSignature \relative c'' {
  \key ais \minor \time 7/4 ais^"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.
