Basically, anyone, regardless of musical background, knowledge or profession can learn to play the SoundStone which we have develpoed. It is necessary to follow the instructions and complete the tasks assigned by the workshop leader, without taking any risks. Playing the SoundStone is dealing with very strong forces which come from the tones and sounds stored in the stone, the Earth´s memory, as one visitor commented. These sounds are picked up by the hands and fingers then spread throughout the body.
