prepared piano,in which objects made of metal, wood, and rubber were attached to a piano's strings, thus altering pitch and tone and producing sounds resembling those of a minuscule percussion group. Cage's Bacchanale (1938) and Sonatas and Interludes (1946–48) were composed for prepared piano. Cage sought to break down the barrier between
nonart,maintaining that all sounds are of interest. Many of his works seek to liberate
nonmusical sounds.For example, 4′33″ (1952), probably his most famous piece, consists of 4 minutes and 33 seconds of silence, providing a frame to be filled by random environmental sounds.
Cage also conceived the idea of a
composition indeterminate of its performance, in which the composer gives the performer instructions that do not directly condition the resultant sounds. For example, his famous Imaginary Landscape No. 4 (1951) is scored for 12 radios tuned at random. In addition, he adopted procedures whereby the composer does not directly condition the sounds of the resultant composition, using such methods as the roll of dice or a consultation of the I Ching (see aleatory music ). Cage, who for many years was associated with choreographer Merce Cunningham , also wrote music for the dance, to be played independently of the choreography. A kind of musical provocateur, Cage is noted for his inventiveness, his humor, and his strong influence on minimalist composers such as Philip Glass and on the development of performance art . His influence also extended to such media as poetry, video art, painting, and printmaking. Cage wrote several books, among them Silence (1961) and A Year from Monday (1967).
