The Prelude in E-flat Major, Op. 23, No. 6 is a 1903 composition by Sergei Rachmaninoff.〔Norris, Geoffrey, ''Rachmaninoff'', Schirmer Books, 1993 (pg. 170).〕〔''Id.''〕 It is part of Rachmaninoff's Ten Preludes, Op. 23. == Structure == The E-flat major Prelude is written in a variation form. An extended sixteenth note accompaniment is offset by a three note reoccurring melodic germ in the right hand. The prelude is a serially reoccurring set of repetitions and variations. Measures 1-9 establish the theme - a parallel period with a cadence in G minor - that continues throughout the piece. The theme is varied in measures 9-20 in G minor, F, E flat, A flat, F, and G. A repetition of the theme occurs at measure 21, and then is drastically simplified. 250px Measure 28 An exchange of ascending and descending chromatic sequences occurs at measures 31 and 32, offset contrapuntally by the changes of the primary theme. 300px Measures 31 and 32 Towards the end of the Prelude, an emphasis is placed on the sixteenth note accompaniment, which expands into two hands, rising upward in a chromatic pattern to the finish. 250px Measures 39-40 250px Measure 19 250px Measure 37 250px Measures 23-24 250px Measures 37-38 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「Prelude in E-flat major (Rachmaninoff)」の詳細全文を読む スポンサード リンク
