Parody

Parody
(PAIR-reh-dee)

A humorous or satirical composition which exaggerates the features of some other composition such as Bach Portrait by P. D. Q. Bach ( Peter Schickele).
A composition where a new text has been substituted for the original as in Fat (after Bad by Michael Jackson) by 'Weird Al' Yankovic.
A Renaissance style of composition, especially prominent in the composition of Masses, in which older material was used in the creation of new music. For a composition to be a parody, it was necessary to incorporate the entire substance of the original material into the new, not merely a tune or a few lines of text.
