is a French poetic form with alternating rhymes and line lengths. Here are basic guidelines:
nine lines per stanza
lines one, two, four, five, seven, and eight have five syllables
lines three, six, and nine have two syllables
the five-syllable lines rhyme with each other and the two-syllable lines rhyme with each other to make the following rhyme patter: aabaabaab
the end rhyme for the short lines continues on in the following stanza
the final stanza’s short-line end rhyme should be the same as the long-line end rhyme in the opening stanza (to complete the end-rhyme circle)
Note on stanzas: This form can contain as few as two stanzas to infinity (if you could write that many).
