Description
This piece explores the tuning fork as a musical instrument in the form of sixteen chromatically tuned forks.
Electromagnetic Acoustic transduction generates sound from a tuning fork without making contact with the tuning fork itself. Electromagnets on either side of each fork (adjacent to each tine) pulse electricity at a specific resonant frequency, which in turn, generates an oceanic swell of sound directly within the material of the tuning forks themselves. This eliminates the need to strike the forks with a hammer which has traditionally been used to generate its sound. The result is a beautifully pure tone, just as a fork oughta be. Without a hammer.
