Chopin's waltz collections are often assemblages of pieces not necessarily from the same period. For example, the Op. 34 trio came from 1831 (No. 2), 1835 (No. 1), and 1838. The three comprising the Op. 70 set were composed in 1829 (No. 3), 1833 (No. 1), and 1841. Surprisingly, though, they show less evolution of style and manner than one might expect.
The first waltz, in G flat major, is vigorous and buoyant, full of color and joy in the outer sections, while the central panel is reflective and nostalgic. The second, in F minor, features one of those Chopin themes that, while generally light in character, is tinged with beautiful melancholy. The brief middle section is brighter and offers effective contrast. The third waltz, the earliest effort here, is the most emotionally neutral of the trio. The main theme is attractive and graceful, demure and cool, while the middle section is livelier and somewhat playful. Each of the three waltzes in the Op. 70 set lasts under three minutes in typical performances.
