Among his six surviving cantatas are Orphee and Le berger fidele.  His instrumental music advanced beyond the style luthe of his predecessors and eschewed chaconnes in favor of rondeaux and binary forms, as seen in works for harpsichord such as Pieces des clavecin and arrangements from his Les Indes galantes. He unsuccessfully attempted to find an overtone-series basis for the minor triad in one of the first works to systematically analyze tonal music theory. This author of the Traite de l'harmonie was a major participant in a dustup prompted by the performance of Pergolesi's opera buffa La Serva Padrona in Paris, the Querelle des Bouffons. For 10 points, name this French Baroque rival of Jean-Baptiste Lully and composer of operas such as Hippolyte et Aricie and Castor et Pollux.
