When might an audience expect to hear an overture? a. at the beginning of an oratorio b. in between movements of a cantata c. after the first movement of a large-scale vocal work d. at the end of an opera

Hi there!

An audience might expect to hear an overture at the beginning of an oratorio. 

Although different overtures appear in different places, it is commonly found at the beginning of an oratorio. 

Hope this helps!

A. At the beginning of an oratorio because at the beginning there is most likely going to be an overture.
