Answer:
In Romeo and Juliet, Shakespeare uses the chorus to provide a narrative overview of the play's events, highlighting key moments and foreshadowing what is to come. The chorus appears at the beginning of each act and serves to contextualize the action and set the tone for the upcoming scenes. Through their speeches, the chorus provides commentary on the themes of the play, and their descriptions of events help to create a sense of dramatic irony for the audience.
Additionally, the use of the chorus helps to make Romeo and Juliet a play that is truly meant to be seen, rather than just read. By providing a visual and auditory experience, the chorus enhances the audience's understanding and enjoyment of the play. This was especially important in Shakespeare's time when many audience members would have been illiterate, and the use of the chorus helped to ensure that everyone could follow the story.
Overall, the chorus in Romeo and Juliet serves to enhance the play's emotional impact and help the audience better understand and appreciate the story being told.
