Libretto

A libretto (from the Italian word libretto, lit. 'booklet') is the text used in, or intended for, an extended musical work such as an opera, operetta, masque, oratorio, cantata or musical. The term libretto is also sometimes used to refer to the story line of a ballet or the texts of major liturgical works, such as the Mass, requiem, or sacred cantata. The Italian word libretto (pronounced [liˈbretto], plural libretti [liˈbretti]) is the diminutive of the word libro ("book"). Sometimes other-language equivalents are used for libretti in that language, livret for French works, Textbuch for German and libreto for Spanish.
