John Milton Cage Jr. (September 5, 1912 – August 12, 1992) was an American composer, artist, and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives. Cage's teachers included Henry Cowell (1933) and Arnold Schoenberg (1933–35), both known for their radical innovations in music, but Cage's major influences lay in various East and South Asian cultures. Through his studies of Indian philosophy and Zen Buddhism in the late 1940s, Cage came to the idea of aleatoric or chance-controlled music, which he started composing in 1951. The I Ching, an ancient Chinese classic text and decision-making tool, became Cage's standard composition tool for the rest of his life. In a 1957 lecture, "Experimental Music", he described music as "a purposeless play" which is "an affirmation of life – not an attempt to bring order out of chaos nor to suggest improvements in creation, but simply a way of waking up to the very life we're living". Cage's best known work is the 1952 composition 4′33″, a piece performed in the absence of deliberate sound; musicians who perform the work do nothing but be present for the duration specified by the title. The content of the composition is intended to be the sounds of the environment heard by the audience during performance. The work's challenge to assumed definitions about musicianship and musical experience made it a popular and controversial topic both in musicology and the broader aesthetics of art and performance. Cage was also a pioneer of the prepared piano (a piano with its sound altered by objects placed between or on its strings or hammers), for which he wrote numerous dance-related works and a few concert pieces. These include Sonatas and Interludes (1946–48).

4′33″ is a modernist composition by American experimental composer John Cage. It was composed in 1952 for any instrument or combination of instruments; the score instructs performers not to play their instruments throughout the three movements. It is divided into three movements, lasting 30 seconds, 2 minutes and 23 seconds, and 1 minute and 40 seconds, respectively, although Cage later stated that the movements' durations can be determined by the musician. As suggested by the title, the composition lasts 4 minutes and 33 seconds. It is marked by silence except for ambient sound, which is intended to contribute to the performance. The length is chosen because 4 minutes and 33 seconds is equal to 273 seconds; -273 degrees Celsius is absolute zero. 4′33″ was conceived around 1947–48, while Cage was working on the piano cycle Sonatas and Interludes. Many prior musical pieces were largely composed of silence, and silence played a notable role in his prior work, including Sonatas and Interludes. His studies on Zen Buddhism during the late 1940s about chance music led him to acknowledge the value of silence in providing an opportunity to reflect on one's surroundings and psyche. Recent developments in contemporary art also bolstered Cage's understanding on silence, which he increasingly began to perceive as impossible after Rauschenberg's White Painting was first displayed. 4′33″ premiered in 1952 and was met with shock and widespread controversy; many musicologists revisited the very definition of music and questioned whether Cage's work qualified as such. Cage intended 4′33″ to be experimental—to test the audience's attitude to silence and prove that any auditory experience may constitute music, seeing that absolute silence cannot exist. Although 4′33″ is labelled as four minutes and thirty-three seconds of silence, Cage maintains that the ambient noises heard during the performance contribute to the composition. Since this counters the conventional involvement of harmony and melody in music, many musicologists consider 4′33″ to be the birth of noise music, and some have likened it to Dadaist art. 4′33″ also embodies the idea of musical indeterminacy, as the silence is subject to the individual's interpretation; thereby, one is encouraged to explore their surroundings and themselves, as stipulated by Lacanianism. 4′33″ greatly influenced modernist music, furthering the genres of noise music and silent music, which—whilst still controversial to this day—reverberate among many contemporary musicians. Cage re-explored the idea of silent composition in two later renditions: 0′00″ (1962) and One3 (1989). In a 1982 interview, and on numerous other occasions, he stated that 4′33″ was his most important work. The New Grove Dictionary of Music and Musicians describes 4′33″ as Cage's "most famous and controversial creation". In 2013, Dale Eisinger of Complex ranked the composition eighth in his list of the greatest performance art works.

Earle Brown (December 26, 1926 – July 2, 2002) was an American music composer, producer, and educator who, as a composer, was a close associate of John Cage, and established his own formal and notational systems. As such, he created "open form," a style of musical construction that influenced composers like John Zorn and the downtown New York scene of the 1980s, as well as later generations of composers. Among Brown's most famous works are December 1952, an entirely graphic score, and the open form pieces Available Forms I & II, Centering, Cross Sections and Color Fields. He was awarded a Foundation for Contemporary Arts John Cage Award in 1998.

The term Number Pieces refers to a body of late compositions (40, or 41 if Seventeen was actually composed) by John Cage. Each piece is named after the number of performers involved: for instance, Seven is a piece for seven performers, One9 (read "One Nine") is the ninth work for one performer, and 1O1 is a piece for an orchestra of 101 musicians. The vast majority of these works were composed using Cage's time bracket technique: the score consists of short fragments (frequently just one note, with or without dynamics) and indications, in minutes and seconds, during which the fragment can start and by what time it should end. Time brackets can be fixed (e.g. from 1.15 to 2.00) or flexible (e.g. from anywhere between 1.15 and 1.45, and to anywhere between 2.00 and 2.30). All of the Number Pieces were composed during the last six years of Cage's life, 1987–1992. Most are for traditional instruments, with six exceptions that range from works for rainsticks, the Japanese aerophone shō and conch shells to an electronically amplified version of 4′33″.
