A-sharp minor or A♯ minor is a minor scale based on A-sharp. The A♯ minor scale has pitches A♯, B♯, C♯, D♯, E♯, F♯, and G♯. For the harmonic minor scale, G
is used instead of G♯. Its key signature has seven sharps (see below: Scales and keys).
Its relative major is C♯ major (or enharmonically D♭ major), and its parallel major is A♯ major, usually replaced by B♭ major, since A♯ major's three double-sharps make it impractical to use. Exceptions include Chopin's Polonaise-Fantaisie in A-flat major, Op. 61, which has a brief passage of about 6 bars actually notated in A-sharp major, inserting the necessary double-sharps as accidentals. The overall harmonic context is an extended theme in B major, which briefly modulates to A-sharp major.
