Final answer:
A metaphor in poetry makes an implicit comparison, stating that one thing is another, and is used to convey deeper meanings.
Step-by-step explanation:
In poetry, a metaphor is used to make a comparison between two things that are not alike but have something in common. The metaphor goes beyond a simple simile, which merely states that one thing is 'like' another, by asserting that one thing is another. This is vividly seen where a poet might write, 'My love, you are a rose,' suggesting not just the likeness but embodying the love with all the attributes of a rose.
To understand the songs as a metaphor in the poem, we must explore the text closely, examining the figurative language and how it relates to the theme. Songs in a poem can be metaphoric for diverse things such as liberation, expressions of the soul, or a call to action, depending on the context given by the poet. An example of a metaphor from the provided text could be 'Chaos is a pinch of joy, a bit of screaming,' which presents chaos as a mix of conflicting emotions. Here, chaos is not just compared to these emotions; it is presented as embodying them.
