The musicians’ approach is based on the latest research, carried out in collaboration with various musicologists. Each new production involves a great deal of ground work, involving the reconstruction of original manuscripts, research into interpretation, concerts, master classes, presentations and recording. Although they show the greatest respect in their interpretation for the both work and the repertoire, they are also capable of breaking free from the established rules and the weight of embellishments in order to find a singing that is profoundly sensual and sensuous.

A Sei Voci is variable in size, with a hard core of six vocal soloists, who are joined by other singers and instrumentalists as performances require. In 1991, the ensemble was recomposed around one of its founders, Bernard Fabre-Garrus. Within just a few years it has built up a fine international reputation in the poyphonic repertoire; in 1994 it was voted "Vocal Ensemble of the Year" at the French Victoires de la Musique Classique. A Sei Voci give about sixty concerts each year in France and abroad, appearing at some of the most prestigious venues. Its recordings on the Audivis/Astrée label (Josquin Desprez, Allegri, Bencini, Janequin, Jommelli) have received numerous awards and wide acclaim from the critics.

The ensemble is also very attentive to musical creation in the present day and has inspired and premièred works by Thierry Escaich, Michel Decoust, Guy Reibel, Michel Levinas and Laurent Cuniot, which have been taken into their repertoire.

A Sei Voci is supported by the City of Sablé-sur-Sarthe, the Sarthe General Council, the Regional Council of the Pays-de-Loire and the French Ministry of Culture.
