  "name": "Indeterminacy and aleatoric (mid-20th-century chance composition)",
  "family": "classical",
  "lineage": "American twentieth-century compositional approach centered on John Cage (1912-1992) employing chance procedures (I Ching coin-tossing, star-charts, environmental noise) to determine compositional material, removing the composer's expressive intentionality. Music of Changes (1951), 4'33\" (1952), Imaginary Landscape No. 4 (1951 for twelve radios), and the Number Pieces (1987-92) constitute the canonical types. Influenced subsequent Fluxus intermedia, conceptual composition, and improvisation traditions.",
