Movie composer Mark Korven wanted to craft the perfect sounds for horror movies, but the instruments he needed didn’t exist, and he was tired of using the same digital samples. To produce the original effects needed for evoking breathtaking moments of suspension, he teamed up with guitar maker Tony Duggan-Smith to craft an original instrument that would better aid in manufacturing fear. The Apprehension Engine is that tool, a mechanism built with several bowed metal rulers, spring reverbs, a few long metal rods, and other attachments that allow for spooky interludes and effects.
“A normal instrument, you are playing it and expecting it to have a sound that is pleasing,” said Korven to Great Big Story, “but with an instrument like this, the goal is to produce sounds, that in this case, are disturbing.”
The Apprehension Engine expresses the emotions that cannot be expressed in other ways, triggering fear with intense sonic methods. You can listen to more music by the machine tuned to provoke horror in the video below. (via Great Big Story)
