Whose opinion did the chorus represent in Greek plays?

In Greek tragedies, the chorus represented the opinion of the common citizenry, the elders, or a specific group closely tied to the plot. They weren't necessarily expressing the playwright's viewpoint directly, but rather a reflection of societal norms, values, and reactions to the events unfolding on stage. Their commentary provided context, offered moral guidance (or sometimes warnings), and shaped the audience's understanding of the play's themes.
