Here's why:
* Meter: Poetry often uses a specific pattern of stressed and unstressed syllables in a line, creating a rhythmic effect. Common meters include iambic pentameter, trochaic tetrameter, and anapestic trimeter.
* Intonation: The way words are spoken, including pauses and emphasis, plays a crucial role in poetry. Intonation can convey emotion, meaning, and emphasis, adding to the overall impact of the poem.
* Rhythm: Poetry relies on the flow and cadence of language, often using rhyme, repetition, and other devices to create a distinct rhythmic pattern.
While prose can have rhythm, it's not as strictly controlled or as central to the writing as it is in poetry. Poetry uses rhythm, meter, and intonation to create a musicality and impact that goes beyond the literal meaning of the words.
