While a couplet is a pair of rhyming lines, it is not a specific type of poetry. A couplet can be used within a narrative poem, but it is not the defining characteristic of one.
Here are some examples of narrative poems:
* Epic poems: Long poems that tell the story of a hero or a nation, such as *The Odyssey* by Homer or *Beowulf*.
* Ballads: Poems that tell a story, often in a simple and straightforward style, and often with a focus on love, adventure, or tragedy.
* Lyric poems: While primarily focused on personal emotion, lyric poems can also tell a story.
* Free verse poems: Poems without a strict rhyme or meter, and can still tell a story.
So, while a couplet can be a part of a narrative poem, narrative poetry is the overarching term for poetry that tells a story.
