A
roundel (not to be confused with the
rondel) is a form of verse used in English language
poetry devised by
Algernon Charles Swinburne (1837–1909). It is the Anglo-Norman form corresponding to the French
rondeau. It makes use of refrains, repeated according to a certain stylized pattern. A roundel consists of nine lines each having the same number of syllables, plus a refrain after the third line and after the last line. The refrain must be identical with the beginning of the first line: it may be a half-line, and rhymes with the second line. It has three stanzas and its rhyme scheme is as follows: A B A R ; B A B ; A B A R ; where R is the
refrain.
