What is the term for a poetic effect achieved by the repetition of initial consonant sounds?

The term for a poetic effect achieved by the repetition of initial consonant sounds is alliteration. This device enhances the rhythm and musical quality of the text, making it more engaging and memorable. It is often used in poetry and prose to create a specific mood or emphasize a particular theme or idea. In contrast, assonance refers to the repetition of vowel sounds within words, which contributes to the internal sound harmony but is distinct from the focus on consonants. Connotation involves the associations and emotional undertones of a word, rather than sound patterns, while diction pertains to an author's choice of words and style. Thus, alliteration is specifically recognized for its auditory effect created by initial consonant sound replication, making it the correct identification in this context.
