The Opera of Dijon Chorus invites amateurs, both young and old, to share the Auditorium stage on the occasion of two concerts each year. The amateur singers of the “ephemeral choir” take part in evening rehearsals once a month and also have the opportunity to meet opera artists and professionals. A similar project is offered to children aged 8 to 12, who form the children’s ephemeral choir. This work culminates in an exceptional performance bringing together more than 150 musicians on the Auditorium stage.
