The Prelude in B-Flat Major, Op. 23 No. 2 is a composition by Sergei Rachmaninoff completed and premiered in 1903.〔Norris, Geoffrey, ''Rachmaninoff'', Schirmer Books, 1993 (pg. 170).〕〔''Id.''〕 == Structure == This brilliant virtuoso piece is rhythmically complex, contrasting thunderous left-hand ostinato against a jagged right hand melodic line. As in Chopin's Revolutionary Etude, the performer must possess considerable left-hand endurance to maintain a consistent ''legato'' throughout the piece. The structural form of the piece is ternary, roughly "ABA" with a coda. The main "idea" of the composition appears in measure 3: Measure 3 Here, the left-hand ostinato continues unimpeded as the treble line, accented and marked ''sempre marcato'' and ''fortissimo'' makes a regal entrance. By measure 20, the kernel of measure 3 is varied drastically, into a transcendent sequence that introduces an inner voice and offsets the main theme. 300px Measure 20 In measures 28-37, the Prelude transitions back to the main theme in a mini-encaptulation of classic first rondo form. The quasi-rondo section forecasts the return of the A section, which is in fact restated in measure 30, albeit disguised in a different key and form. 300px Measure 30 With the exception of measure 52, measures 38-54 are an exact repetition of the main theme. Measure 52 is pure Rachmaninoff: a vertigo inducing cluster no doubt inspired by the composer's stupendous chord-playing technique. 300px Measure 52 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 B-flat major (Rachmaninoff)」の詳細全文を読む スポンサード リンク
