A few years ago, we featured a video, embedded above, that demonstrates a DIY instrument, The Apprehension Engine, designed for creating eerie sound effects.
The Apprehension Engine was commissioned by film composer Mark Korven and built by luthier Tony Duggan-Smith and is described as ‘the spookiest instrument on Earth.’
Since then, Film Masters has shared a series of videos that demonstrate how you can build a DIY Apprehension Engine:
The two dozen videos in the series cover the build in detail, whether you want to create your own Apprehension Engine, or to use the design as inspiration for creating your own custom design.
