ORATORIO
Or`a*to"ri*o, n. Etym: [It., fr. L. oratorius belonging to praying.
See Orator, and cf. Oratory.]
1. (Mus.)
Definition: A more or less dramatic text or poem, founded on some Scripture
nerrative, or great divine event, elaborately set to music, in
recitative, arias, grand choruses, etc., to be sung with an
orchestral accompaniment, but without action, scenery, or costume,
although the oratorio grew out of the Mysteries and the Miracle and
Passion plays, which were acted.
Note: There are instances of secular and mythological subjects
treated in the form of the oratorios, and called oratorios by their
composers; as Haydn's "Seasons," Handel's "Semele," etc.
2. Performance or rendering of such a composition.
