Giovanni Pacini was an Italian composer, best known for his operas. Pacini was born in Catania, Sicily, the son of the buffo Luigi Pacini, who was to appear in the premieres of many of Giovanni's operas. The family was of Tuscan origin, living in Catania when the composer was born.

Opera is a form of theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another.
