Strategic Silence
Removing music, background sound or dialogue from a moment where most films would fill it. The quiet forces you to sit with what is on screen.
Schindler's List
John Williams's score runs through the film, but it drops out completely during the Płaszów liquidation sequences. The silence doesn't feel peaceful. You have to listen to the sounds of the event itself, with no music telling you how to feel.
12 Years a Slave
A conventional historical drama would use music to guide how you feel. In those sequences, McQueen takes Hans Zimmer's score out. You have to sit with the suffering with no soundtrack standing between you and it. The silence puts you in the scene and takes away the protection that movie convention usually gives you.
