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:
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:
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.
