No, this will not be a discussion about running around on your spouse, lover or significant other, and it has nothing to do with a Beach Boy's song from the sixties. This will be a brief discussion of several French forms of poetry that have been translated into English. Much like the villanelle, all of these forms utilize a limited rhyme scheme and feature refrains.
Rondeau
The rondeau, or rondeaux in plural form has two basic restraints from which the poem is built. The first of these is a refrain made up of the first word or words in the first line which must appear in line nine and fifteen of the fifteen line poem. The second restraint is that the remaining non-refrain lines utilize only two rhymes. The thirteen lines also must be written in the same meter, often either in iambic lines of four or five feet.
Sometimes the first five lines form the first stanza, sometimes there is no break until after the ninth line. The following rhyming diagrams will show the layout of the rondeau:
