Which word describes the use of repeated phrases to enhance rhythm?

The use of repeated phrases to enhance rhythm is known as anaphora. Anaphora is a rhetorical device where the same word or group of words is repeated at the beginning of successive clauses or sentences. This technique not only creates a lyrical quality in the writing but also emphasizes the repeated phrase, making it more impactful.

For example, in the famous speech by Martin Luther King Jr., the phrase "I have a dream" is used multiple times to create a powerful rhythmic and emotional effect. By leveraging anaphora, a writer can effectively reinforce a key theme or idea, drawing the audience's attention and creating a sense of urgency or poignancy.

In contrast, parallelism refers to the use of similar grammatical structures in a series, which can also enhance rhythm but does not specifically involve repetition of phrases. Metaphor involves a figure of speech comparing two unlike things, and alliteration refers to the repetition of initial consonant sounds in a series of words, neither of which directly addresses the concept of repeated phrases for rhythmic enhancement.
