The Chœur d’Oratorio de Paris addresses the repertoire best suited to its size and vocation: masses, motets, Requiem and oratorios by Bach, Haydn, Mozart, Mendelssohn, Brahms, César Franck, Gabriel Fauré, Maurice Duruflé, Francis Poulenc, without neglecting the secular repertoire of the 19th and 20th centuries: Schumann, Berlioz, Ravel and many others.
Since its creation, the Choir has been hired by Jean-Claude Malgoire's La Grande Écurie et la Chambre du Roy (Festival des instruments anciens and Festival de la Chaise-Dieu in 1990), and the Orchestre de chambre de Paris, then conducted by Armin Jordan, orchestras with which the Choir has had the opportunity to collaborate many times since then.
Since then, he has participated in numerous productions, being regularly invited by the greatest conductors: (Colin Davis, James Conlon, Theodor Guschlbauer, Jean-Claude Malgoire, John Nelson, Alberto Zedda, Marek Janowski, Tamas Vasary, Jerzy Semkow, Jacques Mercier [fr]) and is associated with renowned soloists including Lucia Valentini Terrani, María Bayo, Barbara Hendricks, Nathalie Stutzmann, Sandrine Piau, Laurent Naouri, François Le Roux, José Cura… The Chœur d’Oratorio de Paris has been invited on numerous occasions since 1992 by the Festival de Saint-Denis,[1] and is collaborating on this occasion with the Orchestre National de France and the Orchestre Philharmonique de Radio France as well as the Orchestre de chambre de Paris.
In 2005, it was again under the direction of John Nelson that the Chœur d'Oratorio de Paris gave Beethoven's Ninth Symphony in concert at the Théâtre des Champs-Élysées in Paris, and in Reims for the opening concert of the "flâneries musicales [fr]".
It then recorded the work as part of a complete discography of the nine symphonies, published in December 2006 by Ambroisie.
