With the help of his father, Tomáš Kropáček began to discover the specifics of playing the clarinet both in the realms of classical as well as jazz music. He strives to continue the work of his Czech Philharmonic predecessors including Vladimír Říha and Karel Dlouhý as well as the methodology of the Czech clarinet school, while approaching it in the light of new aesthetic and technological demands.
