Sometimes the most fascinating musical instruments aren’t found in a music store. Dutch composer Jelle Dittmar has captured the imagination of hundreds of thousands of viewers with a custom-built instrument made from a double bass string stretched through a drainage pipe. In a short but unforgettable video, Dittmar demonstrates the eerie, cinematic sounds the creation can produce, first in its raw form and then layered with effects including reverb, delay, distortion, and flanger. The result is a deep, haunting drone that prompted viewers to compare it to the soundtracks of ‘Dune’, science fiction blockbusters, Viking epics, and dark fantasy films. Whether heard dry or fully processed in a mix, Dittmar’s unconventional creation is a reminder that musical inspiration can come from just about anywhere – even the plumbing aisle.
