Decide if you would like to create repetition primarily through rhyme or by repeating lines within your piece. Formal verse relies heavily on end-line repetition to create a framework, the chorus, as in Poe's "The Raven."
End rhyme is when the last word in a line rhymes with the last word in a following line. Repeating a line simply is not an example of true end rhyme because you are using the same phrase to create the rhyme; true end rhyme introduces a new word or idea.
Determine whether or not you wish to write your poem in free verse (no defined structure or metrical rules) or with a formal verse (a specific style, such as a sonnet that determines the meter and rhyme scheme of your work).
Write line by line, following the rules of formal verse if you have chosen to use a structured style.
Although free verse allows you to use any type of structure you wish to create, you can use end rhyme, assonance (the repetition of vowel sounds) or other poetic devices to help you structure your work while creating repetition. You can check the rhythm and rhyme scheme of your poem by reading the poem aloud at a normal pace.
Omit any cliches or excessive rhyme patterns that take away from poem. On his website for composition and literature students at Carson-Newman College, Dr. Kip Wheeler notes some common rhyme cliches as : love and dove, moon and june, or trees and breeze. An example of an excessive rhyme pattern would be having end rhyme with every line (big, fig, twig, rig, dig). While repetition and structure are helpful tools, too much repetition of a sound or rhythm will be distracting and uninteresting to your audience.
