Classical Chinese poetry forms developing a complete poetic concept; this is, indeed, especially the case with the five-character line version. Also known as the Five-character-quatrain, this form of regulated verse is characterized by four lines of five characters each. Also known as the Seven-character-quatrain, this is a form of regulated verse with four lines of seven characters each. While embracing all, or most of, the "lushi" rules and regulations the "pailu" allows for a number of linked couplets with no maximum upward limit. A strict emphasis on formal parallelism is typical of the "pailu" form. Poems based on traditional structures, originally meant as lyrics
Poetry used at the close of each subsequent stanza until the final quatrain, which is concluded by the two refrains. The remaining lines of the poem have an a-b alternating rhyme. The villanelle has been used regularly in the English language since the late 19th century by such poets as Dylan Thomas, W.H. Auden, and Elizabeth Bishop. A limerick is a poem that consists of five lines and is often humorous. Rhythm is very important in limericks for the first, second and fifth lines must have seven to ten syllables. However, the third and fourth lines only need five to seven.
