A Kyrielle Sonnet consists of 14 lines (three rhyming quatrain stanzas and a non-rhyming couplet). Just like the traditional Kyrielle poem, the Kyrielle Sonnet also has a repeating line or phrase as a refrain (usually appearing as the last line of each stanza). Each line within the Kyrielle Sonnet consists of only eight syllables. French poetry forms have a tendency to link back to the beginning of the poem, so common practise 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. Therefore, a good rhyming scheme for a Kyrielle Sonnet would be:

AabB, ccbB, ddbB, AB -or- AbaB, cbcB, dbdB, AB.
