1. Structural balance: Starting and ending a poem with the same line, phrase, or idea creates a sense of structural balance and symmetry, which can add aesthetic appeal to the poem. It provides a sense of completeness and unity to the poem's structure.
2. Emphasis and repetition: Repeating the same line or idea at the beginning and end of a poem emphasizes its significance and draws the reader's attention to it. Repetition can also create a sense of rhythm, melody, and memorability in the poem.
3. Circular structure: Some poems employ a circular structure, where the ending connects back to the beginning, creating a continuous loop. This structure suggests a cyclical nature or the idea that the poem's themes and ideas are interconnected and self-referential.
4. Frame narrative: Starting and ending a poem with the same line or idea can create a frame narrative, where the poem's main content is enclosed within a specific framework or context. This technique helps shape the reader's perception of the poem's content.
5. Symbolism and allusion: Repeating a particular line or idea at the beginning and end of a poem can create symbolic or allusive connections within the poem. It allows the author to establish deeper layers of meaning and engage the reader in interpreting these symbolic references.
6. Emotional impact: Starting and ending a poem with the same line can create a profound emotional impact on the reader. It reinforces the central themes and emotions explored in the poem, leaving a lasting impression on the reader's mind.
7. Structural experimentation: Some authors use this technique as a form of structural experimentation, breaking away from traditional poetic forms and challenging readers to perceive the poem in a new way.
