Valse Op. 64 No. 2 in C Sharp Minor 圓舞曲作品64之2 升C小調

The Waltz in C♯ minor is a piano waltz composed by Frédéric Chopin in 1847, the second work of his opus 64 and the companion to the "Minute Waltz" (Op. 64, No.1). Chopin dedicated this Waltz to Madame Nathaniel de Rothschild.

It consists of three main themes:
Theme A tempo giusto chordal with a walking pace feel;
Theme B più mosso (faster) — theme stated in running eighth notes, with all harmony in the left hand.
Theme C più lento (slower) — a sostenuto in the parallel key of C♯ minor (D♭ major, enharmonic equivalent to C♯ major). Besides the slower general pace, the melody is in quarter notes except for a few flourishes in eighth notes, giving this section the quality of an interlude before the dramatic restatement of Theme B.
The overall layout of the piece is A B C B A B. In an orchestrated version, it forms part of the ballet Les Sylphides.

升C小調圓舞曲（法語：La Valse en do dièse mineur）是蕭邦的作品64的第二首曲子，與小狗圓舞曲（Op. 64, No. 1）相伴。此曲創作於1847年。蕭邦將這首圓舞曲獻給納撒尼爾·德·羅斯柴爾德夫人。

它由三個主題組成：

主題A tempo giusto 散步感覺的和弦；
主題B più mosso（更快） — 主旋律用流動的八分音符，配上左手的和音。
主題C più lento（更慢） — 轉為與C♯小調異名同音的降D大調。在整體上節奏較慢之外，旋律除少部分八分音符裝飾外，全部都是四分音符，讓重述主題B前的此節有了間奏的水準。
此曲的整體結構是A B C B A B。其管弦樂版本為芭蕾舞曲《仙女們》的一部分。
