Oratorio ورقة الموسيقى

An oratorio is a large scale work for orchestra, choir, and soloists. In most formal aspects its similar to the opera, but the oratorio is meant as a concert piece rather than a form of musical theater. Also, in their beginnings, oratorios tended to use themes from either the Bible or the lives of the Saints, rather than secular stories. The form later opened to extra-religious influences.
