During his musicological studies at the University of Tours, Marc Busnel tackled the repertoire of the Renaissance with the ensemble Jacques Moderne under the direction of Jean-Pierre Ouvrard. At the same time, his musical training and writing studies at the Conservatory of Tours and classical singing lessons with Pali Marinov enabled him to access many musical styles, up to contemporary artistic creations.
After his professional debuts with the ensemble Clément Janequin, he currently performs with the ensembles Musica Nova, Huelgas, Doulce mémoire, Ensemble Solistes XXI (Les Jeunes Solistes), Les musiciens de Saint-Julien, La Main harmonique, Cappella Pratensis, Correspondances, La Sestina, etc. on numerous concerts and recordings, including as soloist.
Marc Busnel has worked under the direction of Jean-Pierre Ouvrard, Paul van Nevel, and Dominique Visse for medieval and Renaissance repertories; Hervé Niquet, Martin Gester, Sébastien Daucé Baroque music; Bernard Têtu for the Classical and Romantic periods; and Marie-Claude Vallin, Roland Hayrabedian, Leo Warinsky, Bruno Mantovani, Peter Eotvös, and Sylvain Cambreling for contemporary music.
His specialization in the music of the Renaissance led him to teaching reading from facsimiles at the CRR in Tours as well as to a collaboration with the Centre d’Études Supérieures de la Renaissance in Tours on the projects Corpus des Messes Anonymes du XV siècle and Atelier Virtuel de Restitution Polyphonique of the musicological research program Ricercar.
