The Planetary Set of 11 tuning forks is calibrated to the tones of the Sun, Moon, Earth, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. The exact tones were calculated by Hans Cousto, the Swiss mathematician, using an octave based on the time for planets to revolve around the Sun. These tuning forks are specifically tuned with cosmological and astronomical timing.
The Sun represents Transcendence, Moon - Sexual Energy, Earth - Relaxation & Meditation, Mars - Creativity, Will Power, Masculine Energy, Venus - Love, Harmony, Feminine Energy, Jupiter - Art & Creation, Neptune - Intuition & Dreams, Mercury - Communication & Voice, Saturn - Concentration & Awareness, Uranus - Spontaneity & Openness, and Pluto - Group & Interpersonal Integration.
