Final answer:
Assonance is the repetition of vowel sounds in words, creating rhythm and mood in poetry, such as the 'a' sound repeated in 'I was walking along the road with two friends...'.
Step-by-step explanation:
Assonance is the repetition of vowel sounds within a word or across words. Often used to enhance the musical quality of poetry, assonance draws attention to particular phrases and can create an emotional response in the reader. For example, in the sentence 'I was walking along the road with two friends the sun was setting - I felt a wave of sadness the Sky suddenly turned blood-red...I felt as though a vast, endless scream passed through nature.', we notice the repetition of the 'a' sound in 'I was walking along' and 'sadness the Sky suddenly'; this repetition of sound is a clear instance of assonance. It creates a rhythm and enhances the mood of the poem. More examples can be found in poems where words with similar vowel sounds are placed in close proximity, for instance, 'my mouth wound itself around the soulful sounds of the poem's words'.
