Answer:
The tone of the poem changes along the lines "The teeming autumn, big with rich increases, bearing the wanton burden of the prime, like widow'd wombs after their lord's decease"
Explanation:
The poem has a tone of melancholy and sadness, but the lines "The teeming autumn, big with rich increases, bearing the wanton burden of the prime, like widow'd wombs after their lord's decease" cause a change of tone. This is because these lines talk about abundance, hope that provides a certain comfort to the reader, but quickly the tone returns to being melancholy, removing this comfort previously achieved.
