Some of Carl Sandburg’s poetry could be referred to as "Walt Whitman pastiche."

A term used in art criticism to refer to a work that borrows heavily from a master’s recognizable style and in music criticism to refer to a medley of known melodies, songs, or musical themes. Pastiche can be used in either way by literary critics, although the former usage is more common. (Most critics use the term descriptively, but some use it to derogate an author’s efforts. When used dismissively, the term describes a work that is deemed highly derivative of someone else’s work or style.) Pastiche may have a humorous, satirical, or serious purpose, but sometimes authors write pastiche simply as a literary exercise. Pastiche should not be confused with plagiarism, in which one author steals a passage or idea from another, passing it off as his or her own and failing to credit the original source. Plagiarism is characterized by deceptive intent; pastiche involves open and intentional imitation or borrowing.

Pastiche is also French for parody; when used as a synonym for parody rather than in its more general, imitative sense, the term refers to a satirical presentation, usually one involving a sustained, parodic imitation of a particular author’s style or technique.

Examples:

• 
  Some of Carl Sandburg’s poetry could be referred to as “Walt Whitman pastiche.”
  
• 
  The American Telephone and Telegraph (AT&T) headquarters building in New York City, designed by noted American architect Philip Johnson, has been referred to as a pastiche. So closely does the top resemble a Chippendale cabinet that the building has, since opening in 1982, been referred to as the “Chippendale building.”

• 
  The setting of the film Moulin Rouge (2001) is Paris at the end of the nineteenth century, but the movie’s anachronistic musical score is a pastiche of late-twentieth-century popular songs such as Elton John’s “Your Song” and Sting’s “Roxanne.”
  
• 
  Through use of the technique known as “sampling” – borrowing riffs from other, well-known songs – rap artists have also created works that involve pastiche in the sense of a “medley.”
  

Choose two paragraphs from the text (or a complete poem, as the case may be). Read it aloud to hear the rhythms created by the writer. Read it again silently, paying attention to: tone and other important stylistic features.

Now, change the subject and write about it imitating the style of the original. In order to become closely familiar with the prose style of the author, you must:

• 
  write about your subject (try to choose something quite different)
  
• 
  follow the exact placement of words and the very same sentence structure, where there is a noun, substitute your own noun; where there are several clauses, or where there is a simple sentence, you must imitate these
  
• 
  end up with exactly the same number of words as the original
