Final answer:
Key differences between a poem and a song include usage of poetic devices, narrative structure, tone and mood conveyance, and author's intent. Poetic devices may be attuned to music in songs, whereas narrative structure in songs typically includes a chorus. The tone and mood in songs are strongly affected by music, while poems rely solely on words.
Step-by-step explanation:
The question asks about differences between a poem and a song. There might be differences in the poetic devices used, the narrative structure, the tone and mood, and the author's intent. While both poems and songs use language artistically, songs often have a musical component that can affect mood and meaning. Poetic devices may be more focused on the sound and rhythm in songs to enhance the musicality, while poems may emphasize imagery and metaphor. Narrative structure in songs is often more repetitive due to the chorus, which is less common in poetry. The tone and mood of a song can be more directly influenced by the music itself, while in poetry, the words themselves must do all the work to convey tone and mood. Lastly, an author's intent in a poem might be more focused on conveying a message or feeling through words alone, while a song might aim to evoke a response through the combination of lyrics and music.
