Definitions of music

An often-cited example of the dilemma in defining music is the work 4′33″ (1952) by the American composer John Cage (1912–1992). The written score has three movements and directs the performer(s) to appear on stage, indicated by gesture or other means when the piece begins, then make no sound throughout the duration of the piece, marking sections and the end by gesture. The audience hears only whatever ambient sounds may occur in the room. Some argue that 4′33″ is not music because, among other reasons, it contains no sounds that are conventionally considered "musical" and the composer and performer(s) exert no control over the organization of the sounds heard. Others argue it is music because the conventional definitions of musical sounds are unnecessarily and arbitrarily limited, and control over the organization of the sounds is achieved by the composer and performer(s) through their gestures that divide what is heard into specific sections and a comprehensible form.
