Alliteration: The repetition of consonant
sounds, typically the initial consonant sound, in a series of words that are located close to one another in a line of poetry or prose. This device creates a strong internal rhythm and enhances the auditory texture of the verse. Alliteration emphasizes thematic connections between words and can unify
a passage musically. It is a fundamental feature of Old English poetry, such as in the epic Beowulf, where it replaces rhyme as the primary organizing sound
pattern. In later English literature, it is used stylistically for effect. For example,
Emily Dickinson employs sibilant alliteration in "
Much Madness is divinest Sense" to create a sharp, intense mood, while
Edgar Allan Poe uses it in "
The Raven" to enhance the poem's musicality and incantatory quality. The
recurrence of similar consonant sounds is distinct from assonance (the repetition of vowel sounds) and consonance (the repetition of consonant sounds anywhere in a word, not just initially).
