In 1959 he was brought by the promoters, to the International Week of New Music in Palermo. The following year, together with other musicians such as Francisco Pennisi and Aldo Clementi, he founded the Nuova Consonanza association and, later, the Gruppo di Improvvisazione Nuova Consonanza. He moved to Berlin for two years (1966–68), hosted by the Deutscher Akademischer Austauschdienst and the Ford Foundation. On returning to Rome, he held a course in experimental electronic composition at the National Academy of Santa Cecilia. In 1972 the obtained an assignment of leading the course in electronic music at the Alfredo Casella Conservatory in Aquila.
In 1974 he was appointed professor of electronic music at the Conservatory of Santa Cecilia in Rome, a post which he held until his death. In those years he gave concerts with the Gruppo di Improvvisazione Nuova Consonanza, in Italy as well as in foreign countries, and continued with conferences and seminars on the “new music”. Compositional activity became less therefore, in order to leave space mostly for research and for theoretical development. At the end of 1979, after nearly twenty years’ work, he finished his book Dal silenzio a un nuovo mondo sonoro (From Silence to a New Sonorous World).
He died in Rome on 28 January 1980. In the early 1960s he famously attacked the lesser followers of the Darmstadt School of composers, of which he was generally reckoned to be a member, accusing them of being merely dodecaphonic police.
