It is a well-known fact that, together with the eyes, the ears perceive a great amount of sensory impressions. However, not many of us know how many interesting sounds can be produced by tapping a stone. The ear helps us to "see" the invisible characteristics of the stone such as hardness, mass and elasticity. Experience of sound is experience of contact. The vibration of the stone is not only conveyed by the eardrum but also via the human skin and - in the case of the Tuning Stone, intensively by the hands.
The Tuning Stone is similar to a large tuning fork. It has two vertical cuts running down two-thirds of its length, and the split elements can be vibrated. This is achieved by lightly tapping the stone with the flat of the hand or by rubbing the stone carefully but firmly with water. This requires a number of attempts and some practice. The participant must achieve an empathy with the stone in order to find the correct frequency, and this enables a living relationship to be made with the otherwise dead, cold material.
Tuning Stone is suitable for public places, parks, pedestrian areas, botanical gardens, town halls, concert halls, material research institutions, educational institutes, department stores, youth centres, suitable institutions for people with special needs, seminar centres, music schools, training and recreational areas of companies.
