Here is yet another well-known example of Chopin's waltzes. The most memorable thing about this waltz is the flowing quaver theme to which it keeps returning after slower interludes with more hesitant themes. The sheet music, midi and mp3 files can be downloaded using the links on the left hand menu. The complete set of Chopin's waltzes for piano is available from Sheet Music Plus (US) or The Music Room (UK).
Like the Grande Valse Brillante Op.18, this Waltz was another of Chopin's piano pieces to be adapted and orchestrated by Alexander Glazunov to create the ballet "Les Sylphides".
