Aldo Clementi (25 May 1925 – 3 March 2011) was an Italian composer.
Aldo Clementi was born in Catania, Italy. He studied the piano, graduating in 1946. His studies in composition began in 1941, and his teachers included Alfredo Sangiorgi and Goffredo Petrassi. After receiving his diploma in 1954, he attended the Darmstadt summer courses from 1955 to 1962. Important influences during this period included meeting Bruno Maderna in 1956, and working at the electronic music studio of the Italian radio broadcaster RAI in Milan.
Poesia de Rilke (1946) was the first work of his to be performed (Vienna, 1947). Of more significance was the premiere of Cantata (1954), which was broadcast by North German Radio (Hamburg) in 1956. In 1959 he won second prize in the ISCM competition with Episodi (1958), and in 1963 he took first prize in the same competition, with Sette scene da "Collage" (1961).
In 1983 David Fanning described Clementi's style of decelerating canons as "sharing in the widespread post-serial depression of the 1970s", while in 1988 Paul Griffiths referred to the "Alexandrian simplicity of his solution to the current confusion in music. Clementi himself described his works as "an extremely dense counterpoint, relegating the parts to the shameful role of inaudible, cadaverous micro-organisms".
His music has been featured at Ultima, the Oslo Contemporary Music Festival (2009), performed and recorded by ensembles including Trio Accanto, the Quatuor Bozzini, the Ives Ensemble and the Contemporary Music Ensemble of Wales and broadcast by BBC Radio 3.
