La serva padrona
In the early 18th century, comic operas often appeared as short, one-act interludes known as intermezzi that were performed in between acts of opera seria. There also existed, however, self-contained operatic comedies. "La serva padrona" (1733) by Giovanni Battista Pergolesi (1710–1736), is the one intermezzo still performed with any regularity today, and provides an excellent example of the style. "Lo frate 'nnamorato" (1732) and "Il Flaminio" (1735), by Pergolesi as well, are examples of the three-act "commedia per musica".
