A provincial composer, Moyreau did not achieve much fame during his lifetime and is almost completely forgotten today.
His most known and most frequently performed piece is Les Cloches d'Orléans, an organ composition that imitates the bells of Orléans Cathedral.
The movements that come after these are usually pieces with descriptive titles, not unlike Couperin's, highly varied in style and mood.
Livre 6, uniquely for French harpsichord music, consists of several three-movement keyboard simphonies written in Italian style.
Contemporary sources also mention a treatise by Moyreau, Petit abrégé des principes de musique par demandes et réponses (1753), which has been conserved at Orléans (Médiathèque), at the Cornell University of Ithaca and at the Newberry Library of Chicago (USA).
