He taught for a while at the Conservatory and the Faculty of Aix-en-Provence, then at the Paul Verlaine University in Metz, before choosing to give lectures independently from 1998 onwards. Fiercely attached to his freedom, he intervenes tirelessly throughout France to share with passion and enthusiasm the fruit of his research, systematically placing music in its socio-historical context.
