How does Edgar Allan Poe use rhythm in The Raven?

Edgar Allan Poe employs a distinctive rhythm in "The Raven" through a combination of trochaic octameter and a consistent rhyme scheme, creating a musical quality that enhances the poem's haunting atmosphere. The use of internal rhyme and repetition, particularly with the refrain "Nevermore," contributes to a hypnotic effect that mirrors the speaker's descent into madness. This rhythmic structure not only emphasizes the poem's themes of loss and longing but also engages the reader emotionally, drawing them deeper into the eerie narrative.
