A burletta (Italian, meaning little joke), also sometimes burla or burlettina, is a musical term generally denoting a brief comic Italian (or, later, English) opera. The term was used in the 18th century to denote the comic intermezzos between the acts of an opera seria, but was sometimes given to more extended works; Pergolesi's La serva padrona was designated a 'burletta' at its London premiere in 1750.
