Whether we’re novelists or short story writers, we’ve probably experienced the irony of how longer writing—such as our story—can sometimes be easier to write than something shorter, like a synopsis, query, Twitter pitch, or log line. The shorter we go, the more every word counts.
That’s why authors often turn to the skills important in poetry to strengthen our writing. In poetry, every word counts for rhythm, imagery, rhyming, etc., so poetry techniques can teach us a lot about how to improve our prose—word by word, line by line.
