But in poetry, rhythm usually sets the poem style, the use of seared, bleared, and smeared is the poetic version of counterpoint. Dr Suess used counterpoint also.

Thank you for using the Jiskha Homework Help Forum. Since I can not see the original post, you may be referring to "spring rhythm" which is an example of internal rhyme and syncopation.

a villanelle is?

A villanelle is a specific form of poetry that consists of 19 lines and follows a strict rhyme scheme and repetitive structure. It is composed of five tercets (three-line stanzas) followed by a quatrain (a four-line stanza). The rhyme scheme is as follows: ABA ABA ABA ABA ABA ABAA. In addition to the strict rhyme scheme, a villanelle also has a repetitive pattern of refrains, with the first and third lines of the first tercet alternating as the last lines of the subsequent tercets, and then forming the last two lines of the quatrain. This repetition of lines creates a unique musicality and emphasis in the poem. Villanelles often explore themes of obsession, longing, or loss. Some famous examples of villanelles include Dylan Thomas's "Do not go gentle into that good night" and Elizabeth Bishop's "One Art."
