Lithophone from chlorite slate
The chlorite slate occurring in the Italian Alps is a metamorphic rock. Basaltic rock has suffered from tectonic subsidence strong pressure and heat in the Earth’s interior and turned into just this shale. Interesting that it is precisely this stone that can give such long echoes.
Trapezoidal sound panels are hit with rubber bobbins or rubbed with wooden and ceramic bobbins.
Spiral lithophone made of chlorite slate
If, as here, 12 plates are cut at an angle of 30 ° and stored next to each other, a circle closes. But when tuning in tone sequences, the plates are getting shorter at higher tones. This creates a spiral – the prototype of all life.
This lithophone is only available in diatonic moods.
Contrabass soundstones made of basalt
1st prize at the 6th Königswinterer Kunsthandwerkertage
Once again a contribution from this participant convinces through his approach to manifold sensory perceptions. An amazing sound effect is achieved by hanging three massive stone slabs of different sizes in front of wooden sounding bodies.
Special cuts in the basalt stones allow different timbres.
The cool rigor of the design stands only in apparent contrast to a warm and deep sound experience. (The jury: Veronika Dietz, Heike Kern, Elmar Scheuren)
made of travertine
8 or 6 cm wide and 2 cm thick stone slabs are mounted on strips with hard foam. The stones are laid out individually. Due to their relatively large weight they can not slip while playing. You bang them with bobbins, but you can also play them with a bow on the edge. Both the Roman travertine and the Swiss serpentinite are excellent soundstones. But in their tonal expression, they are completely different.
