Harrison Instruments designs quality theremins using a variety of technologies, and fabricates prototypes for both consumer-direct and OEM (Original Equipment Manufacturer) requirements. The theremin, named for its inventor, Leon Theremin, was introduced in the 1920s as one of the first electronic musical instruments.
The owner of the company, Arthur Harrison, oversees the design and production of all Harrison Instruments theremins to provide the highest performance for cost, meeting his personal criteria for rugged, reliable and playable instruments.
Theremins are distinguished by the fact that they are played without the performer touching the instrument. The musician moves his or her hands in proximity to the theremin to control the tone of the sound.
While mastering the theremin requires skill, the challenge is exciting, and the rewards are great. Few musical instruments are capable of such intimate expression, nor provide the unique visual appearance of performance.
Harrison Instruments provides theremin parts, modules, and complete instruments. Our standard products include:
The Model 302 Theremin |
The Minimum Theremin Kit 101 |
The 204 Theremin |
The 204 Theremin Printed Circuit Assembly |
The Model 151 Theremin |
Theremin Components and Special-Order Items |
