Aldo Clementi (Catania, Italy, 1925) began his piano studies at the age of thirteen, and received his diploma in 1946 under the guidance of Giovanna Ferro, a student of Alfredo Casella. In 1947, Clementi attended Pietro Scarpini’s piano master class in Siena. At the age of sixteen he started studying composition in Catania, where he later became a pupil of Alfredo Sangiorgi (a student of Schönberg in Vienna in 1922-23), who introduced him to the technique of twelve-tone composition (Catania-Bolzano 1945-52).
