The rime couée is a French poetic form, written as an number of sestets. The poem begins with an eight syllable rhyming couplet, followed by a six syllable line, another eight syllable rhyming couplet, and a final six syllable line. Some list the rhyme scheme as aabaab, ccdccd, etc. Others suggest the rhyme scheme is aabccb, ddeffe etc. Choose the one that works for you!
You can read more about this form at Poetry Magnum Opus and The Poets Garret.
