Composition for Four Instruments (1948) is an early serial music composition written by American composer Milton Babbitt.
 It is Babbitt’s first published ensemble work, following shortly after his "Three Compositions for Piano" (1947).
 In both these pieces, Babbitt expands upon the methods of twelve-tone composition developed by Arnold Schoenberg.
 He is notably innovative for his application of serial techniques to rhythm.
 "Composition for Four Instruments" is considered one of the early examples of “totally serialized” music.
 It is remarkable for a strong sense of integration and concentration on its particular premises—qualities that caused Elliott Carter, upon first hearing it in 1951, to persuade New Music Edition to publish it (Carter 1976, 30).
Milton Byron Babbitt (May 10, 1916 – January 29, 2011) was an American composer, music theorist, and teacher.

Stephen L. (Lucky) Mosko ((1947--) 7, 1947 – 5, 2005(2005--) (aged 57 ) ) was an American composer.
 His music blends high modernism (including serialism) with world music, and he is an expert in Icelandic folk music.
 His, "seemingly contradictory," influences include uptown, downtown, and the West Coast school; including John Cage, Milton Babbitt, Elliott Carter, Morton Feldman, and Mel Powell.
Bethany Beardslee (born December 25, 1925) is an American soprano particularly noted for her collaborations with major 20th-century composers, such as Igor Stravinsky, Milton Babbitt, Pierre Boulez, George Perle, Sir Peter Maxwell Davies and her performances of great contemporary classical music by Arnold Schoenberg, Alban Berg, Anton Webern.
 Her legacy amongst midcentury composers was as a "composer's singer"—for her commitment to the highest art of new music.
 Milton Babbitt said of her "She manages to learn music no one else in the world can.
 She can work, work, work."
 In a 1961 interview for Newsweek, Beardslee flaunted her unflinching repertoire and disdain for commercialism: "I don't think in terms of the public... Music is for the musicians.
 If the public wants to come along and study it, fine.
 I don't go and try to tell a scientist his business because I don't know anything about it.
 Music is just the same way.
 Music is "not" entertainment."

"Who Cares if You Listen?"
 is an article written by the American composer Milton Babbitt (May 10, 1916 – January 29, 2011) and published in the February, 1958, issue of "High Fidelity".
 In addition to being the single most well-known work by Babbitt, it epitomized the distance that had grown between many composers and their listeners.
 In the words of Anthony Tommasini in the "New York Times", "To this day, it is seized as evidence that he and his ilk are contemptuous of audiences" .
Composition for Twelve Instruments (1948, rev. 1954) is a serial music composition written by American composer Milton Babbitt for flute, oboe, clarinet, bassoon, horn, trumpet, harp, celesta, violin, viola, cello, and double bass.
 In it Babbitt for the first time employs a twelve-element duration set to serialize the rhythms as well as the pitches, predating Olivier Messiaen's (non-serial) "Mode de valeurs et d'intensités", but not the "Turangalîla-Symphonie" (1946–48), in which Messiaen used this device for the first time in the opening episode of the movement titled "Turangalîla II".
