Composers

He graduated in piano in 1946 and specialized the following year at Siena with Pietro Scarpini. His compositional studies, begun privately in 1941, continued under the guidance of Alfredo Sangiorgi (a pupil of Schönberg at Vienna) and of Goffredo Petrassi, under whose guidance he took his diploma in 1954.
