So...where 're all the "Danger is near" music ?

[Blackrobin]

It is the terror of anticipation preceeding the revelation of horror that gives the greatest sense of dread.
The danger music can provide that, though this can be achieved without music. Look, for example, this scene from Rear Window

I think the lack of music in that scene let the audience to pay extra attention to the environmental sound and the sound of footsteps which hints the approaching danger.
