Tunelle is a spring instrument.
Springs always ring in several pitches at the same time. Depending on the articulation used, different pitches of the same spring can be brought out more clearly.
Ferrophone creates sound by slowly rotating two metal discs with motors, each disc touching the opposite one with a nail. It can scare you with its metallic, squeaky and mean sounds, but it can also touch you with clear, long ringing and harmonious sounds
PriZm is an enchanting percussion instrument with a singing soul.
Sounds of PriZm in its higher register may remind one of chimes and toy piano. But once the pitch gets lower, PriZm drifts from clear bells into a darker and mysterious world.
