Karel Velebný and the Third Stream

This Master's thesis focuses on the specific features and phenomena in the Czech third stream in the 1960s. These specifics are identified, on the one hand, through the analysis of Karel Velebný's third streams compositions, but also through their comparison with third stream works by other Czech authors in the observed period. The resulting characteristic of the Czech third stream is then confronted with the third stream of an American author and ideological founder of this style movement, Gunther Schuller. The criterion for the inclusion of the analyzed compositions in this thesis was the presence of a certain avant-garde ambition, which, in this thesis, is understood as the use of dodecaphony or other New music compositional techniques in the context of jazz music. In the analysis, the thesis focuses on the way these compositional techniques were implemented into the structure of jazz music, but the author also observes which musical components are through this stylistic synthesis modified the most. Key words: Third stream, jazz, Karel Velebný, Pavel Blatný, Gunther Schulle
