The 221.23 Hz Frequency and Hans Cousto’s Planetary Octave System
The 221.23 Hz frequency was not chosen arbitrarily. Swiss mathematician and musicologist Hans Cousto, in his 1988 work The Cosmic Octave, calculated the orbital periods of the solar system’s planets and raised those periods through successive octaves until they entered the audible range. The result for Venus’s orbital period is 221.23 Hz, a tone Cousto associated with the Ajna, or third eye, chakra and with yin energy: calm, receptive, intuitive, and inward-facing. This planetary tuning system has become the standard reference for a specific lineage of sound healing practice.
Venus in this system does not primarily represent romantic love, a common misconception that leads to confusion between planetary tuning forks and their purposes. The Cousto Venus frequency is associated with the feminine yin principle, with beauty as clarity of perception, and with the kind of receptive awareness that makes genuine intuition possible. For practitioners working with the third eye chakra on intuition, inner vision, and clairvoyance, this frequency is one of the most commonly used single-fork tools in sound healing practice.
Ajna Chakra: What the Third Eye Governs
The Ajna chakra, located between the eyebrows and associated with the pineal gland in Western interpretive traditions, governs inner perception, intuition, and the capacity to distinguish insight from projection. In Tantric and Vedic frameworks, Ajna is the seat of the higher mind rather than the analytical intellect, the place where information from multiple sources resolves into understanding. Its Sanskrit name translates roughly as “perceive” or “command,” reflecting its role as the chakra that integrates sensory and psychic information before passing it to consciousness.
Practitioners working to strengthen Ajna function often report that the challenges are not in opening the chakra but in learning to trust what they receive through it. Sound healing work with the third eye chakra tuning fork, used consistently before meditation or divination sessions, can serve as a pre-practice ritual that orients attention inward.

How to Use the Third Eye Chakra Tuning Fork
How to use the third eye chakra tuning fork at 221.23 Hz for Ajna activation and intuition work.
- Strike the Fork Correctly
Strike the fork gently against the rubber mallet, not hard surfaces. Hold the stem and let the prongs vibrate freely. The 221.23 Hz tone, the Venus frequency in Cousto’s system, fades gradually over about 30 seconds. Do not grip the prongs.
- Apply to the Ajna Point
Bring the vibrating fork to within a few inches of the space between your eyebrows, the Ajna point. Hold it steady and breathe slowly. The resonance is felt as much as heard, and many practitioners report warmth at the third eye point during use.
- Integrate into Your Practice
Use the fork before meditation, divination, or any practice requiring heightened intuition. Strike and hold for one to two minutes, repeating as needed. Store in the included pouch to protect the prongs from bending between sessions.
The Tarot Fellow Standard
I carry this tuning fork because the Cousto planetary system is a coherent, documented framework rather than marketing copy, and practitioners who work with it deserve tools that arrive at the correct frequency. The dark blue color coding matches the traditional Ajna color association, and the included mallet and pouch make this a complete kit rather than just the fork alone. If you are building a chakra sound healing practice, explore my chakra and meditation products for complementary tools that support the full seven-chakra system.
Frequently Asked Questions
Hans Cousto calculated 221.23 Hz in The Cosmic Octave (1988) by raising Venus’s orbital period through multiple octaves into the audible range. He associated it with the Ajna chakra and yin energy, intuitive and receptive in its essential character.
Strike the fork with the rubber mallet, then hold it near the third eye point between the eyebrows. You can also place the stem on a resonant surface to amplify the tone. Sessions of one to two minutes are typical for a pre-meditation warm-up.
Ajna, between the eyebrows, governs intuition, inner perception, and the ability to distinguish insight from projection. It integrates multiple inputs into clear understanding and is linked to the pineal gland in Western interpretive systems.
The fork is 8 1/2 inches in length, crafted from high-quality metal, and includes a protective pouch and a 7-inch rubber mallet. It arrives pre-tuned to 221.23 Hz. The dark blue color corresponds to the Ajna chakra’s color association in practice.
