Stéphane Béchy studied mainly with René Brethomé, and Marie-Claire Alain for the organ, Olivier Baumont and Davitt Moroney for the harpsichord. He performs mainly in recitals throughout the world, and his knowledge of ancient repertoires has led him to teach students at the Rotterdam Conservatory, Northwestern University in Chicago, the University of Belgrade, the Prague Conservatory, the Brno Academy and Seoul University.
