Modern Composition
Also known as Contemporary classical, New music
A broad catch-all for modern concert music that leans experimental, minimalist, or textural rather than strictly tonal or traditional. The label is useful, but it is loose enough that the history should be read as a cluster of related practices rather than a single origin story.

Origins and context
The category is documented as covering 20th-century concert music that developed in the United States and elsewhere, especially through postwar experimentalism and minimalism.

History
AllMusic treats Modern Composition as a wide category for compositional movements that took shape across the 1900s, including minimalism and other avant-garde directions. That makes the style less a single movement than a moving target, shaped by postwar experimentation, new technologies, and composers who wanted to rethink what a concert work could do. In practice, the label overlaps heavily with minimalism and experimental music. Philip Glass’s own site describes Music in Twelve Parts as a major work built from repetition, while Apple Music notes that Glass’s minimalist phase peaked there in 1974; those kinds of works helped define the sound many listeners now associate with modern composition.
