Assonance, alliteration, and imagery are essential literary devices in poetry, enhancing the auditory and visual experience for readers.
Assonance is the repetition of similar vowel sounds within words, creating a melodic effect. An example is in Edgar Allan Poe's poem, where 'weak and weary' uses the 'ee' sound repeatedly.
Alliteration involves repetition of consonant sounds at the beginning of words, like in the phrase 'sweet song of silence,' emphasizing the sound.
Imagery is used to engage the reader's senses and create vivid mental pictures, as seen in 'I Hear America Singing,' where the poem describes various activities of working men and women.
