One dramatic technique that Miller uses to enhance the concepts of the play is music. The flute accompanies most changes in scene and indicates the tone. For example, at the beginning of Act II, the optimisim felt by the characters is paralleled by the sprightly music of the flute. Similarly, the introduction (and reintroductions) of Ben is accompanied by its own music, helping the audience understand that this character is only a figment of Willy's imagination.
Another technique is the use of minimal props and colors. For example, the set of the "fragile-looking" (I) house glows a weak blue is surrounded by towering buildings that glow a reddish color. This color represents strife and anger and threatens to beat through the weak serenity (represented by the color blue) of the home and family. Frequently, significant, symbolic objects are focused upon for the audience's benefit, such as the rubber hose on the gas furnace and the stockings that Linda continually mends. These items are highlighted in the stage directions during times of optimism for the family to seemingly remind the viewers that all is not going to turn out well.
