Hervé Douchy studied cello at the Conservatoire royal de Bruxelles. While working with the RTBF Symphony Orchestra, his encounter with Sigiswald Kuijken led him to take up the baroque cello, which he perfected with Hidemi Susuki. He then pursued a career as a concert musician, playing with numerous Belgian and foreign ensembles: La Petite Bande, Il Gardelino, La Pastorella, Le Concert Royal, Akademia, Le Poème harmonique...and of course Les Agrémens, of which he is a founding member. His meeting with Guy Van Waas opened the doors to higher education for him. Since 1994, he has taught chamber music at the Conservatoire royal de Mons and, since 2006, baroque cello at the Conservatoire royal de Bruxelles.
Thanks to his encounter with Marc Vanscheeuwijck (University of Oregon), Hervé Douchy has developed his baroque cello class towards research in the service of practice. This is reflected in particular in the use of several types of instruments (violin bass, violoncello), played in different positions (seated or standing, in procession, with the bow held below the hand) with different tunings (4 or 5 strings). His research has been enriched by close collaboration with Brussels luthier Pierre Van Engeland for over 20 years. He also plays several instruments made by this luthier.
