Spontaneous Obsessivism John  Zorn’s Cobra

         John Zorn’s Cobra (completed October 9, 1984) is an experimental, unnotated avant-garde game piece rather than a traditional musical scor 
      
The most renowned of John Zorn’s many game pieces, Cobra is one of his landmark works, and the most oft-performed compositions in new music. Completed in October 1984, it premiered to both acclaim and consternation. 
 Cobra (1987 Double Album): Released on Hat Hut Records, featuring live and studio improvisations with a downtown New York ensemble including Bill Frisell, Elliott Sharp, Wayne Horvitz, and Bobby Previte.
Live at the Knitting Factory (1992): Documented landmark avant-garde performances recorded in New York 
The Processs...
The Prompter: A leader (often John Zorn himself) directs the performance using color-coded cue cards and a set of system rules instead of traditional conducting.
 Player Gestures: Musicians communicate with the prompter and each other using specific hand signals and touches to the head or face.
 Inspiration: Zorn designed the system based on a World War II simulation/strategy game and Karlheinz Stockhausen’s Plus-Minus.
 Indeterminate Nature: Instrumentation, the number of performers, and the length of the piece change with every performance.
 Oral Tradition: Zorn intentionally left the complete operational instructions unpublished so they could spread as a live oral tradition among improvisers.
