My application concerns a musical instrument that originated in Africa: the lamellophone, also knows as kalimba, mbira, sanza, etc.
You can use W-05-G cube magnets to make individual sounds lower-pitched when you move the magnets forward on the tongues.
This is an easy way to create strange tunings.
In the video you can see and hear our Made in Switzerland instruments, the magnimba, fitted on a frame drum as a "bio amplifier."
We also introduce the magnimba on our homepage where you can order the instrument.
