D-sharp minor or D minor is a minor scale based on D-sharp, consisting of the pitches , , , , , B, and . For the harmonic minor, the C is raised to C. Its key signature has six sharps. E-flat minor is its enharmonic equivalent. Its relative major is F-sharp major, and its parallel major is D-sharp major, usually replaced by E-flat major, since D-sharp major, which would contain nine sharps, is not normally used. Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. D-sharp minor is infrequently used as the principal key center of pieces in the Classical era. More common is notation in E-flat minor, which is a relatively manageable key for many brass instruments and woodwinds. ==Compositions in D-sharp minor== The most famous work in this key is Scriabin's famous Etude Op. 8, No. 12. The Russian composer Lyapunov wrote the second étude of his Op. 11 set in the key, and also fifteen years later his Variations on a Russian Theme, Op. 49. In addition, his early Piano Concerto No. 1, Op. 4 was in the enharmonic key of E-flat minor. The second movement from Charles-Valentin Alkan's ''Grande sonate 'Les quatre âges''', subtitled ''Quasi-Faust'', is also in D-sharp minor (but ends in F-sharp major), and modulates into even sharper keys along the way, some even being theoretical keys, such as G-sharp major and A-sharp major. In a few scores, 6-sharp key signatures in the bass clef are written with the sharp for the A on the top line. Despite the key rarely being used in orchestral music other than to modulate, it is not entirely uncommon in keyboard music. For orchestration of piano music, some theorists recommend transposing the music to D minor or E minor. If D-sharp minor must absolutely be used, one should take care that B-flat wind instruments be notated in F minor, rather than E-sharp minor (or A instruments used instead, giving a transposed key of F-sharp minor), and E-flat instruments in C minor instead of B-sharp minor, as key signatures do not use double sharps. 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「D-sharp minor」の詳細全文を読む スポンサード リンク
