The Chant Royal is a poetic form that is a variation of the ballad form and consists of five eleven-line stanzas with a rhyme scheme ababccddedE and a five-line envoi rhyming ddedE or a seven-line envoi ccddedE (capital letters indicate lines repeated verbatim). To add to the complexity, no rhyming word is used twice.[1][2] It was introduced into French poetry in the 15th century by Christine de Pizan and Charles d'Orléans and was introduced into England towards the end of the 19th century as part of a general revival of interest in French poetic forms. The complexity of the form caused William Caswell Jones to describe it as "impractical" for common use [2] The Chant Royal was the most complicated form of poetry in Northern France during the 15th century, though not as complex as the sestina, which was more popular in Southern France.[1] The form was often used for stately, or heroic subjects.
