(b Verona, 9 June 1927; d Milan, 17 Aug. 2000). Italian composer. He studied at the conservatories of Milan (1946–8) and Bologna (1948–51), and at the Accademia di S. Cecilia, Rome, with Pizzetti (1952–4). An influential teacher himself, in Italy (particularly at the Accademia Chigiana in Siena) and abroad, he went through successive stages of nihilistic modernism in his music to arrive in the mid-1970s at a playful style most often and variously expressed in small instrumental pieces. In later years he began to write for the voice, producing Arie for soprano and orchestra (1978) and reworking earlier pieces as an opera, Atem (La Scala, Milan, 1985).
