*A Kyrielle Sonnet is a poem that consists of 14 lines (three rhyming quatrain stanzas and a non-rhyming couplet). It has a repeating line or phrase as a refrain (usually appearing as the last line of each stanza). Each line within the Sonnet consists of only eight syllables. French poetry forms have a tendency to link back to the beginning of the poem, so common practice is to use the first and last line of the first quatrain as the ending couplet. This would also re-enforce the refrain within the poem. The rhyming scheme is:
A a b B, c c b B, d d b B, AB -or- A b a B, c b c B, d b d B, AB.
