Which device repeats vowel sounds to shape mood in poetry or prose?

• A. Alliteration
• B. Assonance
• C. Onomatopoeia
• D. Hyperbole

Answer: (B)

Assonance is the repetition of vowel sounds in nearby words, which gives poetry a musical feel and helps set the mood. In a line like “The rain in Spain stays mainly in the plain,” the long vowel sounds weave through the words, creating a soft, lyrical rhythm that can feel playful, dreamy, or melancholy depending on the vowels chosen. This mood-shaping effect comes from the way vowels carry tone and breath in speech, smoothing the line and guiding how the reader feels as they listen or read. This is different from alliteration, which repeats initial consonant sounds, or onomatopoeia, which imitates sounds, or hyperbole, which uses exaggerated statements for emphasis. By focusing on repeating vowel sounds, the writer evokes a musical quality that enhances the emotional texture of the passage.
