Radovanović, Vladan , Serbian composer; b. Belgrade, Sept. 5, 1932. He studied at the Belgrade Academy of Music. His early works were set in a neoclassical style; later he annexed ultramodern techniques, including electronic effects. His Urklang for Mezzo-soprano and Chamber Orch. (Belgrade, March 14, 1962) deploys a counterpoint of instrumental colors, with the soloist singing wordlessly. Similarly wordless is his suite Chorales, Intermezzi e Fuga for Women’s Chorus (Belgrade, May 16, 1962). His experimental period included such innovative works as Sphaeroon for 26 vocal parts, singing detached vowels (Belgrade, March 14, 1962), and Pentaptych, suite for Voice and 6 Instruments (Belgrade, April 22, 1964). He later composed Timbral for Tape (1988).
