One example of a monologue is Juliet's speech in the popular William Shakespeare play "Romeo and Juliet," which began "O Romeo, Romeo! Wherefore art thou Romeo?" A monologue occurs when a single character in a play presents their thoughts out loud to the audience.
When a character presents the spoken thoughts to the audience, there are usually no other characters on the stage. Although, the monologue may also include a chorus in the background. Ancient Greek theater commonly used monologues to indicate the passage of time within a scene. Other types of monologues include entrance and exist monologues and linking monologues.
