Like any modern art movement, contemporary classical music embraces rather than shuns experimentation. In John Cage’s infamous three-movement composition 4’33’’ (1952), the performers sit in silence for 4 minutes and 33 seconds. The “music” is whatever sounds that naturally occur in the environment, from screeching chairs to coughing audience members.
Not all contemporary composers have moved in this direction, though. For every musician seeking to push the conceptual envelope, another uses electronic sounds and other technology innovations simply to build upon or comment on the work of those long-dead composers whose names and melodies continue to come to mind when we use the term “classical.”
