The thesis tries, by means of thematically specified musical-historical and analytical studies, to grasp the chamber works of Karel Reiner (1910-1979) from 1960s and 1970s. In this period, his typical compositional techniques, synthesising the influences of the music between the world wars with new elements, took shape. In the analytical part of the thesis, we attempt to constitute a hermeneutic dialog between our views and the views of Hába and Reiner. First, we always try to explain or reconstruct the meaning of the selected phenomena from the point of view of Alois Hába, then we try to find the use of them in Karel Reiner's chamber compositions.
