A comparison of the scores for Colinette à la cour and Barbe-bleue illustrates the primary distinguishing factor between the genres of comédie lyrique and opera comique: the method of dialogue delivery. In Paris, the issue of genre was tied to the performance venue of a particular opera, due to government regulations. Although comic opera was traditionally presented with spoken dialogue, as in opera comique, when Grétry composed for the Opéra, where recitative was expected, he merged comic subject matter with the sung dialogue heard in serious opera.
