Opera is a vocal genre that originated in Italy around 1600. It combines music, drama, and spectacle to tell a story. Operas are typically performed by a large cast of singers, accompanied by an orchestra.
Oratorio
An oratorio is a large-scale vocal composition for orchestra and soloists, typically on a biblical or religious subject. Oratorios are typically performed in concert halls, rather than in theaters like operas.
Cantata
A cantata is a shorter vocal composition for soloists and orchestra. Cantatas can be on any subject, but they are often sacred in nature.
Chanson
A chanson is a French song, usually for solo voice and lute or other instrument. Chansons were popular in the 16th and 17th centuries.
