Planet Gongs are tuned in conformity with the natural harmonic series based in the orbital properties on the Earth, the Moon, the Sun, and the Planets according to calculations of Hans Cousto.

Thus they resonate in harmony with the cycles of the celestial bodies and communicate a distinct aspect of the “music of the spheres” so amply quoted since the Antique. Their sound color is extremely mysterious and conveys an unusual, unfathomable atmosphere.
