What is alliteration in poetry?

Alliteration in poetry is the repetition of the same consonant sound at the beginning of a series of words. This literary device adds a musical quality to the language and can create a pleasing rhythm for the reader. For example, in the phrase "sally sells seashells by the seashore," the repetition of the "s" sound creates an alliterative effect. Alliteration is commonly used in poetry to create emphasis, evoke certain emotions, and make the language more memorable. It is an important poetic technique that enhances the overall impact of the poem.
