What makes poetry work? Why is it different than fiction and other genres? I’m not sure any scientific answer is possible to this question, since it involves so many elements, many of which simply can’t be measured objectively. But this view hasn’t kept appraisers of literature from trying to say what makes poetry different.
Part of the difference is found in the “music” of poetry–its use of rhythm, rhyme and other features to connect to the reader or hearer of its words.
