This study concerns the declaimed performance of recitative in early French opera. Because the dramatic use of the voice was crucial to the opera genre, this investigation begins with a survey of historical definitions of declamation. Once the topic has been described, the thesis proceeds to thoroughly study three treatises dealing with sung recitation: Bacilly's Remarques curieuses, Grimarest's Traité de recitatif, and Dubos' Reflexions critiques. Principles from these sources are then applied to representative scenes from the literature. The paper closes with a commentary on the relationship between spoken and sung delivery and on the development of different declamatory styles.
