the formal arrangement of rhymes in a stanza or a poem. If it is one of a number of set rhyme patterns, it may be identified by the name of the poet with whom the set rhyme is generally associated (for example, the Spenserian stanza is named for Edmund Spenser). The rhyme scheme is usually notated with lowercase letters of the alphabet (as ababbcbcc, in the case of the Spenserian stanza), each different letter representing a different rhyme.
