What's the difference between poetry and composition?

Poetry is a highly concentrated literary genre that reflects social life. Full of the author's thoughts and feelings and rich imagination. Its language is concise and vivid, with distinct rhythm, harmonious rhyme and rich musical beauty. The sentences are generally in rows and pay attention to the beauty of structural form.

Composition is a style that expresses a theme through words after people's ideological consideration and language organization. Composition is divided into primary school composition, middle school composition and college composition (paper). Composition genres include: narrative, expository, practical and argumentative.

In short, poetry pays attention to rhyme, artistic conception, symmetrical and neat sentence patterns and so on. The composition is not as symmetrical and neat as the non-required format.
