With violist and composer Mahyar Mivetchian, Sénart founded the professional chamber orchestra Les Archets du Roy René in 2005. With this ensemble, he continues to present numerous concerts for a growing number of music-loving audiences in the Pays d’Aix.

                 Apart from the aforementioned Service Sacré by Milhaud, other notable accomplishments during his time in Provence include performances of Arthur Honegger’s Nicolas de Flue, Cantate de Noël and Le Roi David; J.S. Bach’s St John Passion, Mass in B minor, and Christmas Oratorio; Handel’s Messiah, and Mozart’s Requiem and Great Mass in C minor. With the Tübingen Youth Orchestra and some hundred choristers, he conducted the last movement of Beethoven’s Ninth Symphony, marking 50 years since Tübingen and Aix-en-Province became twin cities. Another landmark was his June 1996 performance of Charles Gounod’s Rédemption for the second edition of Polyphonies Françaises en Pays d’Aix, with four hundred and fifty choristers and the Orchestre Lyrique Régional de l’Opéra d’Avignon, an event that took place at the Vitrolles Stadium in front of more than two thousand people. In 1998, he conducted the world premiere of J. Berthier’s Requiem, also recording this work with the Schola St-Sauveur and the titular organist of Aix Cathedral Chantal De Zeew, under the Studio SM label. With the latter vocal ensemble, he also recorded the complete sacred polyphonic works of early 20th-century French composer Mel Bonis, under the Voice of Lyrics label. He conducted Les Archets du Roy René in an independently produced recording of Handel’s Dixit Dominus and excerpts from Messiah.
