# Musical game pieces

> Zorn’s composition takes its name from a simulation game published in 1977 in the war-game magazine, Strategy & Tactics, which simulates “the Allied break-out from the Normandy peninsula in the summer of 1944, which culminated in the encirclement of some 160,000 German troops in the ‘Falaise Pocket’ ” (quoted in Brackett 2010, 44). Both the board game and musical composition provide a set of rules within which players negotiate. More specifically, one of the crucial features of Zorn’s composition is that it provides a formal structure for collective improvisation, rather than any particular musical content, such as a set of harmonies. The piece thus facilitates improvised interactions between musicians with highly contrasting backgrounds and/or aesthetics.

Game piece is a concept of experimental music having its roots with composers Iannis Xenakis, Christian Wolff, John Zorn and Mathius Shadow-Sky. Game pieces may be considered controlled improvisation. An essential characteristic is that there is no pre-arranged sequence of events. They unfold freely according to certain rules, like in a sports game. Therefore, game pieces have elements of improvisation. A number of methods can be used to determine the direction and evolution of the music, including hand gestures. 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. Zorn's game pieces, written in the late 1970s and mid-1980s, include Cobra, Hockey, Lacrosse, and Xu Feng.

Mathius Shadow-Sky (born 1961) developed music gaming system founded on Roger Caillois, Gilles Deleuze, and Lewis Caroll's concepts to create new 'scoring' for music. Starting in 1980 with Ludus Musicae Temporarium for an 'archisonic lamps consort', followed by several music games among them: The Ephemerodes Card of Chrones in 1984 for a broken piano orchestra, a temporal music game based on elastic rhythms interactions (within nonoctave scales for sliding morphing harmony).

As well as a sports game, a game piece may also be considered analogous to language: The performance is directed by a well-defined set of rules (a grammar) but by no means fixed or predetermined (just as all sentences generated by the same grammar are not the same). The length of a piece may be arbitrary, just as a sentence can be of any imaginable length while still conforming to a strictly defined syntax.

In Formalized Music (2001), Iannis Xenakis mentions two pieces in his oeuvre that utilize game theory: Duel (1959) and Stratégie (1962). The first of these, Duel, involves an orchestra that is broken into two groups, each with a separate conductor. Each conductor chooses from a palette of six modules, and points are assigned to each conductor based on the combinations of modules that occurred. Stratégie expands this process to a larger orchestra, and it simplifies the rules to make performance easier.

German experimental group Einsturzende Neubauten developed a 600 card game piece named Dave. Vocalist Blixa Bargeld describes the card game as "not too much of an aleatoric thing as it is a navigation system". Dave is used as an improvisational spur in live performance and was used extensively in the composing and recording of Alles in Allem.

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. Signs consists of twenty-five cards and Images fifteen. The games were released by Brotzmann as a limited edition in 2002.
