Sonic Energy's planet-tuned gongs are manufactured in Germany according to Hans Cousto's calculation (The Cosmic Octave). Each gong is tuned exactly to the frequency of the respective celestial body in order to achieve a therapeutic effect.
These gongs are handcrafted by the gong makers to respond with great sensitivity in all playing applications. Their mysterious sound comes from the countless hours spent handworking the metal. It is atmospheric and soothing.
