Opera is a large-scale music drama that is sung. It combines singing and instrumental music with poetry, acting, scenery, and costumes.
Many elements of spoken theatre, like scenery, costumes, and acting, are used in opera. However, the importance of song distinguishes opera from other dramatic forms.

The plural of the Latin word opus, which means "work," is opera.
