Glass tube chime

is both a percussion and a string instrument. Actually, caress is the right word. Because if you rub it very tenderly with wet hands, a gentle, magical sound is created. I build glass tube chimes in different scales. A total of 3 octaves is possible (g – g”’).

Quartz tube chime


Rubbing it gently with a wet palm at the center of the tube in the transverse direction produces a gentle sound that radiates in all directions and resonates very long. The nice thing is that you can create the sounds directly with your own hand. The vibrations of the tubes can be experienced through the sense of touch.

If you rub the glass tube with just one wet finger near the suspension, the first overtone sounds, which is about an octave and a fourth above the fundamental tone. In a tube, the root and the first overtone can be generated simultaneously. Due to the combination of basic and overtones, many variations are possible.

glas4Quartz is the most abundant mineral in the earth’s crust after feldspar. Amazing that it can give such intense, almost weightless sounds of itself.


Verrophon1Glass soundboards are softly upholstered on an aluminum frame. Struck with felt bells, soft soul sounds sound. In the tenor section, resonators made of acrylic glass hang above the plates. If you sway this slightly while playing back and forth, the sounds swell up and down.
