Composed in 1991, a year before John Cage’s death, Four⁴ was written specifically for recording on CD, which accounts for its seventy-two-minute duration. This final work devoted to percussion quartet belongs to a period in which recorded media were opening new possibilities for composers and listeners.
Written as Cage approached his eightieth birthday, Four⁴ forms part of the “Number Pieces”, a group of works that occupied this composer, philosopher, writer and artist between 1987 and 1992. Cage’s work during these years was supported by computer tools developed by Andrew Culver, his long-standing assistant, helping him respond to the growing demand for new music from performers around the world.
Each title begins with a number written as a word—One, Two, and so on—indicating the number of performers. A superscript distinguishes successive works for the same number of players. Thus Four⁴ is the fourth work in the Four sequence. The first Four was written for string quartet in 1989; Four² is for chorus (1990); and Four³ (1991) is for four performers using one or two pianos, rainsticks, violin or oscillator, and silence. The fourth Four, for percussion quartet, is the work heard on this recording. Cage subsequently wrote Four⁵ for saxophone quartet and Four⁶ for unspecified sound sources.
For listeners unfamiliar with this late music, the contrast with Cage’s more overtly virtuosic and densely eventful works may be striking. Bare, elemental sounds suggest an open landscape and a deep connection between our inner nature and the surrounding environment. The pitches and resonances of individual elements seem to continue sounding in the mind. We cannot know when nature will produce its sounds, any more than we can predict the arrival of the wind. A similar atmosphere emerges in Four⁴ through the spacious use of time brackets.
The time-bracket principle underlies much of the Number Pieces and was also discussed by Cage in his mesostic writings. In Four⁴, as in other works, the choice of percussion instruments is left to the performers. This is not indifference to the result: it accords with the Zen-influenced thinking that informs so much of Cage’s work. Silence, rhythm and repetition become part of an economy of means that invites the players to explore the possibilities of limited materials.
Cage deliberately refrains from determining every aspect of the resulting sound, allowing the performers and the circumstances of each performance to bring something new into being. The flexibility of the time brackets supports this intention. Their structure provides a framework without fixing every event within it, granting a freedom different from that available in conventionally notated music.
In Four⁴, the beginning and end of a sound are separately specified, and each time bracket contains only one sound. The four players have twenty-two, sixteen, ten and fifteen brackets respectively. For example, the first player may begin the opening sound at any point between 0:00 and 1:00, and end it between 0:40 and 1:40. Cage can therefore establish the work’s overall duration while leaving the precise timing of individual events to the performers. Each musician’s decisions, and their changing relationship to one another, make every performance different.
As the brackets unfold, extended stretches of silence emerge. Each decision becomes a choice of peace: a vibrating calm within the storm, interrupted by sound—an inner sound—in an imagined, endless alternation that recalls the breath of the spirit.
