1-4 players. Players pick a major key, preferably a less familiar key. Each player decides on a “zone”, i.e. a range of five adjacent tones. Example in the key of C: Player 1: C D E F G. Player 2: E F G A B. Player 3: A B C D E. Player 4: D E F G A. Choose a comfortable register. Players must stay within this range and share the same beat or pulse; they are encouraged to experiment with the various parameters of music: note value, articulation, register, dynamics, note length, meter. Players should steal much of their material from the other players (rhythm, melodic shape, dynamics, etc.)
Variation 1: Players must only use their “zone” notes, but they may use them in any register.
Variation 2: Try different size zones, e.g. seconds, thirds, fourths, sixths.
Variation 3: Have each player pick a different size zone.
