frmusic1-3, Exercise 2: Types of French opera

Model answer:

Grand opera: large-scale serious opera in five acts with spectacle, a ballet and big choruses, at the Paris Opera; for example works by Meyerbeer.
Opera-comique: opera with spoken dialogue, not necessarily comic, staged at its own theatre; for example Carmen in its original form.
Operetta: light, witty musical theatre with spoken dialogue and satire; for example Offenbach's Orpheus in the Underworld.

Gounod's Faust may be given as a lyric opera. Check the attributions against a reference work.
