This is a six-second cut of the pulsing dun-dun motif, driven by a heavy metallic beat and a cold, marching rhythm. It feels tense, relentless and faintly menacing, as if something powerful is closing in, yet it can turn an ordinary moment darkly comic. The motif comes from Brad Fiedel's score for Terminator 2: Judgment Day, released in 1991.
