Composers such as Boulez, Stockhausen, and Nono were writing their music in the aftermath of World War II, during which many composers, such as Richard Strauss, had had their music politicised by the Third Reich.
Heliloojad nagu Boulez, Stockhausen ja Nono kirjutasid oma muusikat Teise maailmasõja järelmõjudes, mil mitmete heliloojate nagu näiteks Richard Straussi muusika oli politiseeritud Kolmanda Riigi poolt.
