Born in Toruń, he studied composition with Kazimierz Sikorski and piano with Stanisław Szpinalski at the State High School of Music in Łódź. He continued his studies in composition with Nadia Boulanger and in piano with Lazare Lévy in Paris (1947–48). Until 1952 he was an active pianist. Afterwards he devoted himself exclusively to composition. A member of Group 49, founded together with Tadeusz Baird and Jan Krenz after the composers’ conference in Łagów, in the 1950s he contributed to what was then regarded avant-garde explorations. He wrote a twelve-tone Suite of Preludes for piano as early as 1952.
Kazimierz Serocki was a co-founder of the Warsaw Autumn Festival. His distinctions included the State Award, 1st Degree (1952, 1972), the Minister of Culture and Arts Award (1963), and an honourable mention at the UNESCO International Rostrum of Composers’ in Paris.
