The chorus is a feature in classical drama, especially Greek tragedy. It refers to a group of performers who comment on the main action of the play, often through song, dance, or recitation.

Functions of the Chorus in Drama:

• Narration: They provide background information to help the audience follow the story.

• Commentary: They interpret events, express public opinion, or make moral judgments.

• Mood Setting: Through their songs or chants, they create the atmosphere of scenes.

• Foreshadowing: They hint at future events or the consequences of characters' actions.

While some poems may have a refrain or repeated lines (similar to a chorus), it’s not the same concept as in drama.
