Rola przypadku w twórczości Witolda Lutowsławskiego. W nawiązaniu do myśli Michała Hellera

In the preface to his book „Philosophy of Chance”, Michael Heller writes that „the structure of the universe is twined with chances”. An analogical structure can be found in classical music, e.g. in the most of works written after 1960 by Witold Lutosławski (1913-1994) – „the biggest Polish composer of the second half of the 20th century, or maybe even the whole century” (Tadeusz Kaczyński). The goal of this paper is to describe in rough the role of indeterminacy in Witold Lutosławski’s controlled aleatoric music and to show analogies between the ways indeterminacy is presented in Lutosławski’s music and Heller’s thought.
