Poetry Guide: Chain Rhyme
A number of verse forms use chain rhyme as an integral part of their structures. One example is terza rima, which is written in tercets with a rhyming pattern a-b-a, b-c-b, c-d-c. Another is the virelay ancien, which rhymes a-a-b-a-a-b, b-b-c-b-b-c, c-c-d-c-c-d.
Other verse forms may also use chain rhyme. For instance, quatrains can be written to the following pattern: a-a-b-a, b-b-c-b, c-c-d-c.
