Although most of Chopin's nocturnes are in an overall ternary form, quite often the individual sections (either the A, the B, or both) are in binary form, most often of the asymmetrical variety.
Selv om de fleste af Chopins nocturner overordnet set er skrevet i tredelt form, er de enkelte sektioner (enten A, B eller begge) ofte i binær form, hyppigst den asymmetriske type.
