Thanks to Luce-Varlet, artistic life was very intense in Douai. In the summer of 1832 Coussemaker set up a "Société d’émulation musicale" ("Society for Musical Competition") in order to play his own pieces of music and those of other local composers with a grand orchestra: Victor Lefebvre, Henri Brovellio, Charles Choulet and Amédée Thomassin. This occurred during the winter when concerts were organised by this society and from 1840 to 1843. As Chief Commissioner of the "Société Philharmonique de Douai" ("Philharmonic Society of Douai") responsible for the recruitment of artists, he invited very prestigious people like the violinist Henri Vieuxtemps or the oboist player Stanislas Verroust to perform. On 5 December 1832 his Romance for two voices was performed: an "Air varié" for oboe, "Chant" for two voices "a cappella" and an "Air" for soprano with accompaniment by an orchestra. He also left manuscripts such as an essay about musical composition and fugue and an essay about harmony, which have apparently both been lost.
