A-sharp minor or A minor is a minor scale based on A-sharp. The A minor scale has pitches , , , , , , and . 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-sharp major. Its parallel major is A-sharp major, usually replaced by B-flat major, since A-sharp major has 4 sharps and 3 double sharps. 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. The direct enharmonic equivalent of A-sharp minor is B-flat minor. Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. A-sharp minor is one of the least used minor keys in music as it is not a practical key for composition. The enharmonic equivalent B-flat minor, which has five flats as opposed to A-sharp minor's seven sharps, is usually used instead. == External links == * (Overview of Compositions with 7 Accidentals ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A-sharp minor」の詳細全文を読む スポンサード リンク
