You should be able to comment on how Williams uses music for dramatic effect.

Music suggests Blanche’s mental state: ‘The   is heard, its music rising with   rapidity as the bathroom door opens slightly’ (Scene Eight, p. 82).

Ask yourself: Why and how is this particular piece of music repeatedly used?

Possible answer: The ‘Varsouviana’ is a polka tune that was playing when Blanche’s husband broke away from her and shot himself. Williams uses it to suggest her obsession with this moment. Only Blanche, and the audience, can hear it, which draws the audience into empathising with her.
