Phonetic Poetics / Verse
Phonetic Poetics are concerned with how words sound when spoken aloud. Traditional poetic forms were often concerned with numbers of stressed and unstressed syllables, and rhyme. Assonance is a satisfying technique that echoes a vowel sound, as in Sylvia Plath's "Mushrooms": "soft fists insist on heaving the needles".
Verse offers so much elite jargon that a longer treatment here is pending; we love jargon.
