What do you call a musical work for chourus orchestra and soloists?
An oratorio is a large-scale musical composition for chorus, orchestra, and soloists, typically based on a religious or spiritual theme. Oratorios are similar to operas in terms of their structure and use of music, but they differ in that they do not include any staging or acting. Instead, the story is told through the music and the words of the libretto. Oratorios have been written by many famous composers, including Handel, Bach, and Mendelssohn.
