The study analyses the role of František Sedlák (1916-2002) in the process of forming didactics of music education and music psychology as independent disciplines and teaching subjects at pedagogical faculties in the former Czechoslovakia. It traces the significant moments in his life that formed the basis of Sedlák's theoretical insight and useful practical experience.
Sedlák's conception of the didactics of music education and music psychology is analysed in detail and the interconnection of music psychological and pedagogical approaches is emphasised.
