Krzysztof Knittel’s text about his own composition techniques, also looking at such topics as: the influence of painting on his music (e.g. the works of Piet Mondrian and Paul Klee); truth in the musical work; the application of recycling ad re-use techniques to the form of the musical work; methods of constructing the sound of the composition; links between music and historical events; rollage - a technique borrowed from the painter Jiří Kolář for the needs of St. Matthew Passion; sound installations created by Knittel with sounds of nature and civilisation; Theodor Lipps’ theory of empathy (Einfuhlung), as well as intuitive and improvised music.
