what is a rhyme scheme

A rhyme scheme is the pattern of rhymes at the end of each line in a poem or song. It is represented using letters to indicate which lines rhyme with each other. For example, a rhyme scheme of AABB means that lines 1 and 2 rhyme with each other, and lines 3 and 4 rhyme with each other. Different types of rhyme schemes can create different rhythms and structures within a poem.
