The Fondation Etrillard supports the Elles - Women Composers association in a common goal to rediscover heritage in innovative ways.
One of the sponsored projects, the Boîte à Pépites, offers the public the opportunity to discover the life and work of composers through drawing and animation. The foundation also supports the Un Temps pour Elles festival, which includes a summer edition, a winter digital edition, and concerts that showcase repertoires of little-known composers.
