Game piece is a concept of experimental music having its roots with composers Iannis Xenakis, Christian Wolff[need quotation to verify] and John Zorn.
Zorn's game piece "Cobra", which has been recorded several times for various labels, uses a combination of cards and gestures and can be performed by an ensemble of any size and composition.
In Formalized Music (2001), Iannis Xenakis mentions two pieces in his oeuvre that utilize game theory: Duel (1959) and Stratégie (1962).
[3] German experimental group Einsturzende Neubauten developed a 600 card game piece named Dave.
[4] Free jazz saxophonist Peter Brotzmann devised, designed and illustrated two card games, Signs and Images, in the early 2000s to be used by the Chicago Tentet.
