Rondeau \Ron*deau"\, n. [F. See {Roundel}.] [Written also
{rondo}.]
1. A species of lyric poetry so composed as to contain a
refrain or repetition which recurs according to a fixed
law, and a limited number of rhymes recurring also by
rule.

Note: When the rondeau was called the rondel it was mostly
written in fourteen octosyllabic lines of two rhymes,
as in the rondels of Charles d'Orleans. . . . In the
17th century the approved form of the rondeau was a
structure of thirteen verses with a refrain. --Encyc.
