Answer Details
A dramatic composition or musical play in which many or all the words are sung is called an "opera". In an opera, the story is typically conveyed through music, singing, and sometimes dance, rather than through spoken dialogue. The singers in an opera are accompanied by an orchestra, and the music is often composed specifically for the production. Operas can be performed in a variety of languages and can cover a range of subject matter, from tragedies to comedies.
