Century Dictionary and Cyclopedia

1. n. A form of extended dramatic composition in which music is an essential and predominant factor; a musical drama, or a drama in music. ; ; . The opera is one of the chief forms of musical art; on many grounds it is claimed to be the culminating musical form. At least it affords opportunity for the application of nearly every known resource of musical effect. Its historical beginning was doubtless in the musical declamation of the Greeks, especially in connection with their dramatic representations. The idea of a musical drama was perpetuated during the middle ages under the humble guise of mysteries or miracle-plays, in which singing was an accessory. The modern development began in Italy near the close of the sixteenth century, when an attempt was made to revive the ancient melodic declamation, an attempt which led directly to the discovery and establishment of monody and harmony in the place of the medieval counterpoint, of the recitative and the aria as definite methods of composition, and of instrumentation as an independent element in musical works. The modern opera involves the following distinct musical constituents, combined in various ways: recitatives, musical declamations, mainly epic or dramatic in character, with or without extended accompaniment
2. n. The score or words of a musical drama, either printed or in manuscript; a libretto.
3. n. A theater where operas are performed; an opera-house.
4. n. The administration, revenue, and property of an Italian church or parish.
5. n. Specifically, a ballad-opera (see def. 1).
6. n. Plural of opus.
