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.
      [1913 Webster]

   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.
