Surprise: A little alteration, variety
“I shall sleep, and move with the moving ships,
Change as the winds change, veer in the tide.”
Algernon Charles Swinburne, The Triumph of Time
Write a piece in which you make use of repetition (not as a formal element, though. Don’t, for instance, begin each line with…Because). Entire words or portions of words, but enough to make a strong echo.
Write in couplets. Don’t simply break your piece into two-line blocks—let each two (roughly) equal lines be capable of standing alone, carrying a thought, even though your sentence may carry over into the next couplet.
Alternate couplets and quatrains. It doesn’t have to be an epic, just long enough to give a sense of pattern. [You can use short lines.]
