Born in Bielsko-Biała, he studied at the State High School of Music in Katowice in the composition class of Henryk Mikołaj Górecki (graduating with honours) and the accordion class of Joachim Pichura. He won awards in numerous competitions, including the Young Composers’ Competition of the Polish Composers’ Union (1976), Artur Malawski Competition (1976, 1980), Carl Maria von Weber International Competition in Dresden (1978, 1979), competitions in Digne-les-Bains (1981, 1987), and Ancona (1986).
He received commissions from Krzysztof Penderecki for the Penderecki Festival in Lusławice (Symphony no. 2 for strings), a Witold Lutosławski grant (1986), and a scholarship from the Scottish Art Council (1988).
He taught at the Katowice Academy of Music for almost a quarter of a century, lectured on modern techniques of accordion playing at Darmstadt (1984–90) and ran courses at the Time of Music Summer Academy in Viitasaari, Finland (1987).
Having made a spectacular debut at the Young Musicians for a Young City Festival in Stalowa Wola in 1975, Andrzej Krzanowski won a reputation as one of the key figures of what has been called the Stalowa Wola generation, the 1951 Generation, and the “new Silesian school.” He died in Czechowice-Dziedzice.
