Zarys problematyki determinizmu i indeterminizmu w muzyce drugiej połowy XX wieku w kontekście przemian myśli naukowej i filozoficznej
The Sketch on the Issue of Determinism and Indeterminism in Music of the 2nd Half of the 20th Century in the Context of Transformation of the Academic and Philosophical Thought

Summary/Abstract: In the second half of the 20th century, integral serialism and rational way of thinking were considered as an indicate of determinism in music. At the same time, indeterminism was associated with the music composed with the use of chance operations, classified like that by Henri Pousseur in his reading entitled Theorie und Praxis in der neusten Musik, delivered in Darmstadt in 1958. However, certain music pieces show that the demarcation between determinism and indeterminism in music remains unclear. The author attempts to outline the problem of determinism and indeterminism in avant-garde music of the second half of the 20th century, taking into consideration selected crucial compositions and the context of development in science and philosophy of that time.
