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

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.
