Movement and sound
Marble musical instruments and diabase moving objects.
According to nature law stone is static. How can it move?
Hanging from the branch of a tree is moves with the wind. Placed on the spring of a shock absorber it moves as well. The frequency of the movement depends on the size and the resistance of the spring and the weight and model of the stone.
I intend to use as much old/recycled materials as possible. The local blacksmith welds the steel springs, which I find at the car dump, on the iron harrow discs, which Salorino agricultors save for me.
The musical instruments do produce a sound if touched with a woodden or metal stick. My friend Alonso Gomez, mason, has made the cuts with a 1 meter diameter disc.
