Background

At the beginning of the 20th century, composers of classical music were experimenting with an increasingly dissonant pitch language, which sometimes yielded atonal pieces. Following World War I, as a backlash against what they saw as the increasingly exaggerated gestures and formlessness of late Romanticism, certain composers adopted a neoclassic style, which sought to recapture the balanced forms and clearly perceptible thematic processes of earlier styles (see also New Objectivity and social realism). After World War II, modernist composers sought to achieve greater levels of control in their composition process (e.g., through the use of the twelve-tone technique and later total serialism). At the same time, conversely, composers also experimented with means of abdicating control, exploring indeterminacy or aleatoric processes in smaller or larger degrees. Technological advances led to the birth of electronic music. Experimentation with tape loops and repetitive textures contributed to the advent of minimalism. Still other composers started exploring the theatrical potential of the musical performance (performance art, mixed media, fluxus). New works of contemporary classical music continue to be created. Each year, the Boston Conservatory at Berklee presents 700 performances. New works from contemporary classical music program students comprise roughly 150 of these performances.
