The association "Et voilà!" has been active since 2002, the year of its creation. Its mission is to promote music through practice (choirs, brass bands, ensembles) and by organizing concerts, festivals, celebrations, and other events. It is particularly committed to introducing classical music to venues and communities that rarely encounter it. It is also especially dedicated to bringing together amateur and professional musicians and creating participatory concerts. The association has numerous achievements to its credit: — "Chœurs en vrac", an annual choral festival — "Jeudi ? C'est musique!", a monthly cycle of narrated concerts at the town hall of the 18th arrondissement — The "Paris Piano Festival", an annual piano festival featuring concerts and open stages — Concert series in media libraries aligned with their event themes — "Les voix des crèches", a CD recorded by childcare workers in Paris — Participatory concerts with amateur singers and musicians
