What is the rhyme scheme used in Sir John Suckling's "Song"?http://dsteinbe.intrasun.tcnj.edu/Courses/BritLit/RenTopic/prithee.htm

John Suckling’s “Song” is a trochaic meter meaning it is using  A front stressed two syllable foot.  Another example of this type of pattern would be Longfellow’s “The Song Of Hiawatha.“By the shore of Gitche Gumee,By the shining Big-Sea-Water,At the doorway of his wigwam,In the pleasant Summer morning,Hiawatha stood and waited”However, the rhyme scheme for “Song” appears to be a quatrain with the abab and alternates four stress and three stress. 

"Why so pale and wan, fond lover?
  Prithee, why so pale?
Will, when looking well can't move her
  Looking illprevail?
  Prithee why so pale?"

Suckling may have done this to make light of the whole idea of love.  He was being sarcastic and decided to make the poem less formal by reversing the stress pattern which is opposite of the more traditional iambic pentameter. "Suckling produced a number of enduring works of satiric love poetry, brief pieces that generally feign indifference to passion and offer a cynical view of romantic relations between men and women."
