La serva padrona
Similar foreign genres such as French "opéra comique", English "ballad opera", Spanish "zarzuela" or German "singspiel" differed as well in having spoken dialogue in place of "recitativo secco", although one of the most influential examples, Pergolesi's "La serva padrona" (which is an intermezzo, not "opera buffa"), sparked the "querelle des bouffons" in Paris as an adaptation without sung recitatives.
