Everything is frequency.
The chair you are sitting in. The screen you are reading. The heart beating in your chest. Each one vibrating at a specific rate — a measurable, quantifiable oscillation that defines what it is at the most fundamental level. Nikola Tesla understood this when he said that to understand the universe, one must think in terms of energy, frequency, and vibration.
This is where my work begins. And it is where many sessions end — with a sound so precise that the body recognizes it before the mind has time to analyze what is happening.
A tuning fork is a simple instrument. Two prongs of metal, calibrated to vibrate at a single, exact frequency when struck. The sound it produces is pure — free of harmonics, free of distortion. One frequency. One truth.
In my practice, I use a set of seven tuning forks, each calibrated to the specific frequency of one of the body’s seven primary chakras — the energy centres that run along the central axis of the body, each governing a different domain of physical, emotional, and spiritual experience.
396 Hz — Root Chakra. Grounding, safety, survival, the foundation upon which everything else rests.
417 Hz — Sacral Chakra. Creativity, emotional flow, relationships, the body’s centre of feeling and connection.
528 Hz — Solar Plexus Chakra. Personal power, confidence, self-worth, the seat of agency and will.
639 Hz — Heart Chakra. Love, compassion, forgiveness, the bridge between the lower and upper energy centres.
741 Hz — Throat Chakra. Expression, truth, communication, the voice of the authentic self.
852 Hz — Third Eye Chakra. Intuition, perception, inner knowing, the gateway to what lies beyond the visible.
963 Hz — Crown Chakra. Spiritual connection, divine purpose, the highest expression of who you are.
These frequencies are ancient — recognized across healing traditions for thousands of years and increasingly validated by modern research into the effects of sound on cellular structure, water molecules, and the human nervous system.
When a tuning fork calibrated to a specific chakra frequency is struck and brought near the body, something remarkable happens. The chakra — which is itself a spinning centre of energy, vibrating at its own frequency — begins to entrain to the fork. It synchronizes. It remembers what it is supposed to sound like. And it returns to its natural, coherent state.
This is resonance. And it is one of the most powerful and gentle healing forces available.
In my sessions, the tuning forks typically arrive at the close of the energetic work — after trapped emotions have been identified and released, after misalignments have been corrected, after the Belief Code has delivered its messages from the chakras.
I move through each of the seven chakras in sequence, beginning at the root and ascending to the crown. At each centre, the fork is struck twice.
The first strike releases. It clears any remaining imbalances or blockages — residual energy that may still be present after the session’s deeper work. The sound moves through the chakra like a gentle wave, carrying with it whatever is ready to go.
The second strike fills. It delivers the correct frequency to the chakra, allowing the energy centre to receive and integrate the vibration it needs. The chakra is brought into alignment — tuned, the way a musician tunes an instrument, to the precise note it was always meant to hold.
Two strikes. Release and receive. The same arc that governs the entire session — clear what is held, install what is true — expressed in sound.
Here is the detail that changes how people understand this work.
The tuning fork does not produce the same volume at every chakra. The state of the chakra determines the sound.
When a chakra has just received a belief statement through the Belief Code — when the throat chakra, for example, has delivered the message “I express my feelings because it is important to me” — the 741 Hz tuning fork will ring at that chakra with a clarity and volume that stands apart from the others. The chakra is open. It is resonant. It is, in a very real sense, singing back.
Conversely, when a chakra is blocked or misaligned — carrying trapped energy that has yet to be addressed — the tuning fork at that centre will vibrate with a noticeably softer sound. Even when struck with more force. Even when the practitioner applies greater energy to the strike. The fork still resonates more quietly.
The force of the strike is irrelevant. The state of the chakra determines the volume.
This is something clients can hear with their own ears. They do not need to believe in energy healing. They do not need to understand chakra theory. They simply need to listen — to the difference between a fork that rings full and clear at one centre and whispers at another — and their body provides the evidence directly.
The fork is an instrument. The body is the orchestra. And the sound that emerges when the two meet tells both practitioner and client exactly where the energy is flowing freely and where something is still being held.
The idea that sound affects the body at a cellular level is increasingly supported by research — and it extends far beyond the subjective experience of feeling calmed by music.
Dr. Mitchell Gaynor, an oncologist and clinical professor at Weill Cornell Medical College, pioneered the integration of sound healing into mainstream medical practice. His research documented the effects of specific sound frequencies on cellular function, stress hormone levels, and immune response — demonstrating that sound is received by the body as a physiological event, processed at the level of tissue and cell, rather than as a purely psychological experience.
Cymatics — the study of visible sound — demonstrates this visually. When sound frequencies are directed through a medium such as water or fine sand, they produce geometric patterns of extraordinary precision and beauty. Each frequency produces a different pattern. Higher frequencies produce more complex geometries. The sound is literally organizing matter into coherent structure.
The human body is approximately 60% water. When a tuning fork calibrated to a specific frequency is brought near the body, the sound waves move through that water — through every cell, every tissue, every fluid system — organizing and harmonizing at a level far beneath conscious awareness.
This is why sound healing often produces effects that feel disproportionate to the simplicity of the instrument. A single fork. A single frequency. A body that is mostly water. The interaction between these three elements is far more profound than the simplicity of the tool would suggest.
Among the seven chakra frequencies, 528 Hz holds a particular place in both ancient tradition and modern research.
Known as the Solfeggio frequency of transformation and healing — and sometimes called the Love Frequency — 528 Hz has been the subject of scientific inquiry that extends well beyond the healing arts. Research by Dr. Leonard Horowitz and others has explored the relationship between 528 Hz and the molecular structure of water, DNA repair mechanisms, and the resonance patterns found in nature — including the frequency at which bees buzz and the mathematical proportions found in healthy organic systems.
In my practice, 528 Hz corresponds to the solar plexus chakra — the centre of personal power, confidence, and self-worth. It is the chakra that most commonly holds beliefs like “others have power over me” and “I am powerless.” When those beliefs are released and the 528 Hz fork sounds at the solar plexus, clients frequently describe a warmth spreading through the stomach area, a sense of expansion, and a quiet but unmistakable feeling of returning to themselves.
The frequency is doing what language cannot — speaking directly to the energy centre in the tone it was designed to receive. The body does not need to translate. It simply recognizes.
You do not need a tuning fork to begin working with sound and your chakra system. You carry an instrument with you everywhere — your own voice.
This practice takes five minutes. Find a quiet space. Sit comfortably with your spine straight and your feet on the floor.
Beginning at the root and moving upward, place your hand on the area of each chakra and hum — a low, steady tone for the root, gradually rising in pitch as you move upward through sacral, solar plexus, heart, throat, third eye, and crown.
At each centre, hold the hum for three slow breaths. Feel the vibration of your own voice in your hand. Notice where the hum feels full and resonant and where it feels thin or effortful. The centres where your voice flows most easily are your most open chakras. The centres where the sound wants to catch or diminish are the ones asking for attention.
When you reach the crown, sit in silence for one full minute. Allow the residual vibration to settle through your entire system.
This practice is a conversation between your voice and your body. Over time, as you repeat it, you will notice the thin places becoming fuller — the sound strengthening where it was once quiet. That strengthening is your energy system coming into coherence, one frequency at a time.
If something in this post has resonated — if the idea that your body responds to precise frequencies, that your chakras hold specific vibrations, and that sound can restore what has been disrupted — I invite you to experience it directly.
My article Why Emotional Patterns Repeat explores how trapped emotional frequencies persist in the body and what becomes possible when they are addressed at the level where they actually live.
Sessions are available in person in Bowmanville and Toronto, and worldwide via Zoom. In-person sessions include the full chakra tuning experience — seven forks, seven frequencies, each one speaking directly to the energy centre it was made for.
Your body already knows its own frequency. The tuning fork simply reminds it.
