; Theoretical Movements
: '''The Second Viennese School''' → Schoenberg, Berg, and Webern (The masters of Serialism).
: '''The Darmstadt School''' → Post-WWII composers (Stockhausen, Boulez) who pushed serialism to its logical extreme.
: '''The New York School''' → John Cage and others who focused on Zen, silence, and chance.
: '''Spectralism''' → French movement (Grisey, Murail) that used computers to analyze the physics of sound to build harmonies.
