Final answer:
Edgar Allan Poe's poem "Annabel Lee" is written in the ballad form, known for its narrative style, quatrains, and regular rhyme scheme that tells a tragic story.
Step-by-step explanation:
The poem "Annabel Lee," by Edgar Allan Poe, uses the ballad poetic form. This form is characterized by a narrative that is often tragic and consists of quatrains with a rhyme scheme, usually alternating lines of iambic tetrameter and iambic trimeter. Given that the poem "Annabel Lee" follows a similar structure with its narrative style, regular meter, and rhyme scheme, it falls under the category of a ballad rather than blank verse, a sonnet, or free verse. A ballad typically has quatrains with an ABAB or ABCB rhyme scheme, and Poe's poem maintains a similar pattern with its musical quality and its story of a tragic love, which is quintessential of the ballad tradition.
