Theorbist Marek Kubát gained his first musical experience at the age of ten, when he began to become acquainted with playing the guitar as a self-taught person. Later, he studied this instrument at the Elementary Art School in Tišnov with teacher Miroslav Ševčík and privately with Stanislav Juřica, a professor at the Pardubice Conservatory. He gained knowledge in the field of jazz guitar and harmony through lessons with jazzman Vilém Spilka. He studied lute at the Academy of Early Music in Brno under the pedagogical guidance of Miloslav Student. He completed lute master classes (Paul Beier, Michael Fields). From the age of fifteen he moved on the concert stage with bands of various orientations (eg folk-oriented Malevil, jazz-rock Ha-Band, jazz Mañana, Czaldy-Waldy quartet playing world music, etc.).
At present, in addition to chamber projects, he regularly performs with various baroque ensembles (Capella Ornamentata, Concerto Aventino, Ensemble Damian, Hof-musici, Musica Figuralis, Silva Rerum arte (PL), Societas Incognitorum). In addition to interpreting baroque music, he also often collaborates with composers of contemporary music (Tomáš Hanzlík, Dada Klementová, Matěj Kroupa, Katarzyna Szwed, Emil Wojtacki, Vít Zouhar). As a lutenist, he is invited to the baroque music projects of the Polish Bałtycká Philharmonic.
