How does each poet use word choice to create tone and imagery?

Answer:

Lowell uses concrete language and focuses on specific images, such as birds and changing seasons, to create a personal tone by using the first-person "I." In contrast, Longfellow uses a combination of concrete and abstract language along with many images. Longfellow’s speaker addresses "us," which creates a more abstract and preachy tone compared to Lowell's personal approach.
