"James Tenney was born in 1934 in Silver City, New Mexico, and grew up in Arizona and Colorado, where he received his early training as a pianist and composer. He attended the University of Denver, the Juilliard School of Music, Bennington College (Bachelor's degree 1958), and the University of Illinois (Master's degree 1961). His teachers and mentors have included Eduard Steuermann, Chou Wen-Chung, Lionel Nowak, Carl Ruggles, Lejaren Hiller, Kenneth Gaburo, Edgard Varèse, Harry Partch, and John Cage.

A performer as well as a composer and theorist, Tenney was co-founder and conductor of the Tone Roads Chamber Ensemble in New York City (1963-70). He was a pioneer in the field of electronic and computer music, working with Max Mathews and others at the Bell Telephone Laboratories in the early 1960s to develop programs for computer sound-generation and composition. He has written works for a variety of media, both instrumental and electronic, many of them using alternative tuning systems.

Tenney is the author of several articles on musical acoustics, computer music, and musical form and perception, as well as two books: META + HODOS: A Phenomenology of 20th-Century Musical Materials and an Approach to the Study of Form (1961; Frog Peak, 1988) and A History of 'Consonance' and 'Dissonance' (Excelsior, 1988). He has received grants and awards from the National Science Foundation, the National Endowment for the Arts, the Ontario Arts Council, the Canada Council, the American Academy and Institute of Arts and Letters, the Fromm Foundation, the Deutscher Akademischer Austauschdienst, and the Jean A. Chalmers Foundation.

Tenney returned to the California Institute of the Arts in the fall of 2000 to take the Roy E. Disney Family Chair in Musical Composition, having taught there at its beginnings in the early 1970s. He has also been on the faculties of at the Polytechnic Institute of Brooklyn, the University of California at Santa Cruz and at York University in Toronto where he was named Distinguished Research Professor in 1994.

James Tenney's music is published by Sonic Art Editions (Baltimore) and the Canadian Music Centre, and is also distributed by Frog Peak (Lebanon, New Hampshire). Recordings are available from Artifact, col legno, CRI, Hat[now]ART, Koch International, Mode, Musicworks, Nexus, oodiscs, SYR, Toshiba EMI, and New World, among others."

"John Milton Cage Jr. (September 5, 1912 - August 12, 1992) was an American composer, music theorist, writer, philosopher, and artist. 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 American 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 is perhaps best known for his 1952 composition 4′33″, which is performed in the absence of deliberate sound; musicians who present the work do nothing aside from being present for the duration specified by the title. The content of the composition is not "four minutes and 33 seconds of silence," as is often assumed, but rather 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. The best known of these is Sonatas and Interludes (1946-48).

His 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 on changing events, 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"."
