The rhyme scheme is the pattern that rhymes follow in a poem, a song or any other text written in verse. It is possible to discover this pattern by looking at the end of each line of verse. The scheme is written by using letters to indicate which lines rhyme. The letters are given in alphabetical order (a, b, c...) and the lines that rhyme with each other receive the same letter. In this case, the rhyme scheme of the poem is "ababb."
