A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

The tremenkan is the world's first electronic musical instrument, invented by former Soviet physicist Professor Lev Termen in 1919. It is the only electronic instrument in the world that does not require physical contact. Using an antenna and the player's hand to form a capacitor, different audio signals within the audible range are generated through the frequency difference between two oscillators. The playing technique lies in adjusting the pitch and volume through the distance between the hands and the antenna, making it the only instrument in the world that can be played without physical contact.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
