What is the term for the pattern of rhyme in a poem?

The term "rhyme scheme" refers specifically to the pattern of rhymes at the end of each line in a poem. It is a systematic way to describe how rhymes are arranged throughout the piece. This can be identified by using letters to denote matching end sounds; for example, in a poem with an ABAB rhyme scheme, lines one and three end with one sound, while lines two and four end with another.

Understanding the rhyme scheme is crucial, as it plays a significant role in the overall structure and musicality of the poem. It can help convey emotions, set the tone, or enhance the aesthetic quality of the writing. In contrast, the other terms in the question—such as alliteration, which refers to the repetition of consonant sounds at the beginning of words; meter, which pertains to the rhythm and structure of the lines; and dialogue, relating to conversations between characters—do not specifically address this concept of rhyme patterns. Thus, "rhyme scheme" is the correct term for the pattern of rhyme in a poem.
