How are operas divided?

Operas are often divided into acts, which are then further divided into scenes. Acts serve as major structural divisions in an opera and are typically separated by intermissions. Scenes transition the narrative forward within each act. The number of acts and scenes can vary depending on the length and complexity of the opera, but most operas consist of two or three acts.

In addition, some operas may also include a prologue or an epilogue. These serve as introductory or concluding sections that set the stage or wrap up the story, respectively.
