Joonas Kokkonen

Finnish composer Joonas Kokkonen (1921-1996). Even though he studied at the Sibelius Academy, he was largely self-taught in composition. Usually his compositions are divided into three style periods: a neo-classical early style from 1948 to 1958, a relatively short middle period twelve-tone style from 1959 to 1966, and a late "neo-Romantic" style of free tonality which also used aspects of his earlier style periods, which began in 1967 and lasted for the rest of his life
