what is ab rhyme scheme
A rhyme scheme is the pattern of rhymes at the end of each line of a poem or song.It is usually referred to by using letters to indicate which lines rhyme; lines designated with the same letter all rhyme with each other. basic distinction is between rhyme schemes that apply to a single stanza, and those that continue their pattern throughout an entire poem (see chain rhyme). There are also more elaborate related forms, like the sestina-which requires repetition of exact words in a complex pattern.
