My definition: Parody is not a genre or collection of genres. Instead, parody is a technique, probably hardwired in all of us, that tweaks, re-channels, transforms, or invents artistic conventions by banging, binding, or blending material into paired, unlikely contrasts. The result is art that is wildly dualistic, multistable, and, frequently, reflexive. Because of the upheavals it creates, the parodic technique is the principal source of technical innovation and change in all the arts, the fountainhead of new genres and modes as well as the core of many masterpieces. Parody is the art that plays with art.
