 "The day is reset dozens of times in the film and it would get very repetitive to approach that musically the same way every time", Beck recalled.He initially tried for "traditional heroic themes" that involved horns and trumpets, but he said Liman "preferred a non-traditional approach, driven by percussion and distorted orchestra".To that end, Beck used the pizzicato playing technique, "not in the traditional, plinky-plinky-isn't-this-funny way, but a little darker, and always accompanied by some higher concept synth colors".
