The Lorentz Violin
The Lorentz Violin makes sound using a spinning magnetic disc that rotates at different frequencies in front of a guitar pickup. The player adjusts a slider to control the speed of the disc, changing the notes the instrument is playing, which are then played through a built-in speaker. It produces whirly, organic tones that feel like a mix between what you’d expect from a weird synthesizer and the sounds of an ancient warped record.
