  • Opera (English plural: operas; Italian plural: opere) is an art form in which singers and musicians perform a dramatic work combining text (called a libretto) and musical score, usually in a theatrical setting.[1] Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance.
