Answer:
Assonance
Step-by-step explanation:
The sound device illustrated in the bolded text is assonance. Assonance refers to the repetition of vowel sounds within words in close proximity. In this excerpt, the assonance is evident in the repetition of the short "i" sound in the words "bright," "wind," and "springing." The repetition of the vowel sound creates a musical and melodic quality in the poem, contributing to its overall rhythm and tone.
