Plunderphonics is a term
coined by composer
John Oswald in 1985 in his
essay Plunderphonics, or Audio Piracy as a Compositional Prerogative. It has since been applied to any
music made by taking one or more existing
audio recordings and altering them in some way to make a new
composition. Plunderphonics can be considered a form of
sound collage.
