The Requiem can be seen as providing the emotional release for the audience (required in a tragedy) in its reflective tone.
Aristotle
For Aristotle, the climax of a tragedy should act as an emotional release for an audience, help to purge (relieve them of) the emotions of pity and fear built up through the tragedy.
The Requiem
Miller’s short closing scene (the Requiem) can be seen as providing such a release for audiences in its reflective tone.
The characters have had the opportunity to reflect on Willy’s life and death and therefore offer judgements which help characters such as Biff, and so audiences, to move forward.
Resolution
But as many commentators have argued, there is no ‘neat’ resolution at the end of the play.
Both of Willy’s sons are in conflict while Linda still cannot comprehend Willy’s death.
