Stephan Koncz comes from an Austro-Hungarian family of musicians and when he was eight began his studies at the Musikhochschule of his native Vienna. In 2000 he became a pupil of Róbert Nagy at the Vienna Conservatory, and from 2002 he also studied composition and conducting at the University of Vienna. His training and development were also decisively stimulated by masterclasses with Daniel Barenboim, Steven Isserlis, Heinrich Schiff, Olaf Maninger and Tamás Varga as well as by chamber-musical activities with Julian Rachlin, Dmitry Sitkovetsky and the 12 Cellists of the Berlin Philharmonic.
