01 / Overview

The exhibit the process of steel balls hitting metal needles to produce music, reflecting the three elements of sound: timbre, pitch (determined by frequency), and loudness (determined by amplitude).

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 / The science behind it

Steel balls of different sizes roll onto a disc and collide with metal needles of varying lengths, producing different sounds and rhythms that produce high, medium, and low notes; Because the steel ball has never traveled the same route twice, you will hear a new melody every time.

04 / 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.
