Accentus is a French chamber choir founded by Laurence Equilbey in 1991.
[2] When in Rouen, the choir usually holds concerts at the Théâtre des Arts or the recently reopened Chapelle Corneille.
Performing mostly contemporary compositions, the choir has collaborated with conductor Eric Ericson since 1996, and has been in résidence at the Rouen Opera House since 1998.
Following the world success of Pascal Dusapin's creations Granum sinapis (1998) and Dona eis (1998) and the French creation Outis (1999) by Luciano Berio, Accentus went on a world tour accompanied by the Ensemble InterContemporain founded by Pierre Boulez, which took them to different countries including the United States.
The choir also accompanies large symphonic orchestras, under the direction of Pierre Boulez, Jonathan Nott and Christoph Eschenbach, as well as the Orchestre de Paris, the Ensemble InterContemporain and the Rouen Philharmonic Orchestra.
