7 Planetary Crystal Singing Bowls – 12" Cosmic Chakra Set (Hans Cousto Tuned)

Celestial rhythm made audible — seven planetary voices in harmonic dialogue.

This 7-piece Planetary Crystal Singing Bowl set is meticulously tuned according to the calculations of Hans Cousto, author of The Cosmic Octave, aligning each bowl with the mathematical frequencies of celestial cycles. Crafted from high-purity white frosted quartz, each 12-inch bowl carries a sandblasted planetary symbol representing its corresponding frequency.

When gently tapped or played with the included silicone-coated rod, each bowl produces a rich, spherical tone with long-lasting resonance. The 12" diameter allows for deeper projection and sustained vibrational presence, making this set suitable for dedicated meditation spaces, professional sound work, and immersive studio environments.

Each bowl is precisely tuned to harmonic relationships that allow the full set to be played together without sonic conflict. Certain planetary frequencies are doubled into higher octaves to maintain tonal cohesion while remaining faithful to Cousto’s calculations.
