The literary term that best matches a group of four rhyming lines is called a quatrain. A quatrain is a type of stanza in poetry that consists of four lines usually with a specific rhyme scheme. In most cases, the quatrain uses an AABB or ABAB rhyming pattern, meaning that either the first and second lines rhyme with each other, followed by the third and fourth lines rhyming together, or the first and third lines rhyme with each other followed by the second and fourth lines rhyming together. Quatrains are commonly used in various forms of poetry such as sonnets, ballads, and other lyrical compositions.
