Burletta
In theater and music history, a burletta (Italian, meaning "little joke", sometimes burla or burlettina) is a brief comic opera. In eighteenth-century Italy, a burletta was the comic intermezzo between the acts of an opera seria. The extended work Pergolesi's  was also designated a "burletta" at its London premiere in 1758. In England, the term began to be used, in contrast to burlesque, for works that satirized opera but did not employ musical parody. Burlettas in English began to appear in the 1760s, the earliest identified as such being Midas by Kane O'Hara, first performed privately in 1760 near Belfast, and produced at Covent Garden in 1764. The form became debased when the term burletta began to be used for English comic or ballad operas, as a way of evading the monopoly on "legitimate drama" in London belonging to Covent Garden and Drury Lane. After the passage of the Theatres Act 1843, which repealed crucial regulations of the Licensing Act 1737, use of the term declined. List of theatrical Burlettas
