movie scenes without scores?

Some suggestions...

In the film CACHE (dir: Michael Haneke), there's a scene where Daniel Auteil's character goes to speak to his mother. The conversation is filmed at length, and you do start to feel the scene running on after a little while. Perhaps some very subtle music could characterise what Auteil is thinking in that scene, particularly in the second half? The film as a whole has no music.

In the film THE CLAIM (dir: Michael Winterbottom), there's a scene where the railroad company men (led by Wes Bentley) come to the town of Kingdom Come to clear out their property. The local landlord (Peter Mullen) and sheriff attempt to stop them by force, and a brief shootout ensues. The film uses no music in this scene from memory, although Michael Nyman did write music for it. Perhaps score the scene for its suspense/standoff potential.

In the film PERSONA (dir: Ingmar Bergman), there's a scene where Bibi Andersson (playing the nurse) tells the story of a sexual encounter to her patient. The monologue is quite famous, and if you've ever seem Andersson deliver it, you'll know why. From memory, there is no score here, but something that alludes to the enveloping erotic rhythms of lovemaking wouldn't be out of place. (Look at Nicole Kidman's two monologues in Kubrick's EYES WIDE SHUT as an indication of the way music might work in the Bergman scene.)
