In the poem "The Old Man's Beard" by Burton Raffel, there are several examples of assonance. For example, in the line "The old man's beard is a silver stream," the vowel sound "e" is repeated in the words "beard" and "stream." In the line "The old man's eyes are a deep blue sea," the vowel sound "i" is repeated in the words "eyes" and "sea."
Assonance can be used to create a sense of rhythm and musicality in a poem. It can also be used to emphasize certain words or phrases. In "The Old Man's Beard," the assonance helps to create a vivid and memorable image of an old man's beard.
Here are some additional examples of assonance in "The Old Man's Beard":
* "The old man's beard is a silver stream"
* "The old man's eyes are a deep blue sea"
* "The old man's hands are like gnarled roots"

These examples show how assonance can be used to create a sense of rhythm and musicality in a poem. They also show how assonance can be used to emphasize certain words or phrases.
