Serial & Aleatoric Music After 1945 | Cage, Stockhausen & the Avant-Garde | Complete High School Music Unit

Serial & Aleatoric Music After 1945 is a complete, no-prep upper-secondary music unit: six lessons with five differentiated worksheets and full answer keys, three student reading texts, a detailed teacher lesson plan and an editable presentation — print and digital, ready to teach.

After 1945 the avant-garde split in two directions that look opposite and turn out to be related: total pre-ordering of every parameter, and the deliberate surrender of control to chance. Students work through Darmstadt serialism and Cage's chance operations, read graphic scores, and reconsider what a composer, a performer and a listener actually do.
