Born in Angers, Moreau was a choirboy at the Cathédrale Saint-Maurice d'Angers, and it was there that he received his musical education.
He worked in Langres and Dijon for short periods, before moving to Paris to become a court musician.
Moreau contributed original music to the premieres of the final two plays of Racine, Esther and Athalie.
[1] Moreau also composed musical interludes for Duche's Jonathas, Boyer's Jephte, Absalon, Debora and various divertissements.
He was also active as a teacher and counts among his pupils Louis-Nicolas Clérambault, Jean-François Dandrieu, and Michel Pignolet de Montéclair.
