Healing Frequencies of the Ancient Solfeggio Scale
Early in the 11th century, an Italian Benedictine monk, Guido of Arezzo, was looking for ways to teach melodies and harmonies to monastic choirs. One of his methods was a mnemonic tool, called the “Guidonian Hand.” Notes were associated with places on the fingers and palm. Once mastered, a choirmaster could point to his hand to inform singers of the next note. This was a new way to teach music — but Brother Guido continued to innovate.
Finding a way to express a musical scale, he created staff notations to teach chants and hymns. Guido’s original notations were “UT RE MI FA SOL LA,” derived from the first syllable of each half-line of the ancient “Hymn to Saint John the Baptist,” descended from an even more ancient work by Horace, an 8th century BC Roman poet.
This scale of six notes (C, D, E, F, G, A), the ancestor of our “so re mi fa so la ti do,“ evolved into the modern diatonic scale after “UT” became “DO” in the 19th century, and “TI” (B) was added later. “Solfeggio” is based on the word “solfège,” the name for this notation method of teaching pitch and sight singing.
Solfeggio Healing Frequencies
Gregorian chants have a measurable influence on human psychology and physiology. Those who perform the chants experience the lowest heart rates and blood pressure of the day while singing, according to Dr. Alan Watkins, a neuroscience lecturer at Imperial College, London. Other research suggests that singing the ancient compositions relieves fatigue and alleviates depression. Scientists have also observed that monastic singers require much less sleep; as little as two hours a day.
Solfeggio Geometry and Cymatics
Cymatics is the science of observing the effects of sound and frequency on matter usually in the form of liquid or powder. The term was coined by Swiss scientist Hans Jenny, who used specialized equipment that allowed a viewer to observe shapes formed in a medium under the influence of sound wave frequencies.
A cymascope study for SomaEnergetics, a company specializing in education and equipment for sound therapy, recorded cymatic images of each of the Solfeggio frequencies. Each frequency image contained “nodes” and “antinodes,” or the tops and bottoms of visible standing sound waves.
Counting the antinodes, the researchers discovered discovered that most of the Solfeggio frequencies, precisely produced by tuning forks, are “divisible by 3, 6, and/or 9. Any whole number divisor of 72 carries a mathematical relationship between phi and certain frequencies; 12, 9, 8, 6, 3, and 2 all work.” 12, 9, 6 and 3 all have special significance in many number-based esoteric systems. And coincidentally, the hz frequency numbers (396, 417, 528, 639, 741, 852) can all be reduced to one of these numbers (369 = 18 = 9, 417 = 12 = 3, 528  = 15 = 6, 639 = 18 = 9, 741 = 12 = 3, 852 = 15 = 6).
Nikola Tesla said, “If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe.” The researchers added that distortions in the images were the product of ambient background noise, but the structure and geometry of each frequency is apparent in the images.

Benefits of the Solfeggio Frequencies
Dr. Joseph Puleo, a physician and herbalist, began exploring the Solfeggio in the 1990s. He developed a theory that each of the six frequencies carried precise characteristics, and that the tones could be used therapeutically.
In 1988, Biochemist Glen Rein, Phd, converted and recorded Solfeggio scale Gregorian chants to scalar audio waves. The results were played to test tubes containing DNA. By measuring UV light absorption, Rein could document the effect of the music on DNA. He also compared the chants with other forms of music, including rock. While rock music had little or no influence, the chants caused a marked increase of light absorption, up to nine percent, leading Rein to conclude that Solfeggio scale sound frequencies cause resonance in DNA, and may have healing properties.
Since then, others have explored the healing potential of the Solfeggio frequencies. According to an article in Anti-Aging Medical News (Winter 2006), pulsed frequencies had a positive impact on osteoporosis. In another study, snails exposed to a range of frequencies, including some in the Solfeggio range, became more focused and active compared to a control group. “It was evident that exposure enhanced the creative capacity of the brain in snails,” the author wrote.
A Japanese study published in 2018 examined the stress reducing effect of 528 hz (MI or E) on the endocrine system. The researchers concluded that 528 hz music has “an especially strong stress-reducing effect, even after only five minutes of exposure.”
Using the Frequencies
Youtube has countless Solfeggio meditations that integrate the frequencies with music — over a million pages were returned in a Google search on “Solfeggio meditation.” Some websites offer expensive, specialized equipment — others offer precisely calibrated tuning fork sets. Some health practitioners strike the forks, then place them on specific acupuncture points and meridians while others create “sound baths” with gongs and singing bowls tuned to specific frequencies.
Someone wishing to experience the Solfeggio frequencies can spend a little or a lot, but a Youtube search and a good pair of headphones may be the best entry point for exploring the Solfeggio frequencies.

What Are Reiki Symbols And What Are They Used For?
Reiki symbols are energetic tools used by practitioners to channel and direct vital energy during a session. Each symbol is used with a specific purpose, such as balancing the body, calming the mind, or facilitating emotional healing. They are incorporated into the practice through visualization, hand-drawn gestures, or mental focus, and they assist in the healing process according to the goal the practitioner seeks to achieve.
Each of these symbols serves a specific function within the system. Some are designed to enhance the energy flow, others to release emotional blockages, relieve mental burdens, or even send Reiki to people who are not physically present. This functional diversity allows each session to be adapted to the recipient’s needs, working on different levels as required by the situation.
In addition to being support tools, the symbols give structure and direction to the therapeutic process. They are not used automatically but as part of a practice that requires attention, presence, and intention. Their strategic application allows the practitioner to guide the session more clearly, effectively, and with greater organization, deepening the effects of Reiki and facilitating a more holistic experience.
Origin And Evolution Of Reiki Symbols
The origin of Reiki symbols dates back to the late 19th century, when Mikao Usui developed this healing system in Japan. Usui integrated teachings from various spiritual traditions and meditative practices, from which the first symbols used in Usui Reiki emerged. These were transmitted privately, only to students who received direct initiations with the master.
Over time, the symbols began to spread beyond Japan thanks to Usui’s disciples and, later on, to the work of teachers like Hawayo Takata, who brought Reiki to the West. In this process of diffusion, the symbols were adapted, documented, and shared with a wider audience, which allowed Reiki to become established as a global practice.
Today, Reiki symbols are part of a path that has expanded far beyond its original lineage. Some contemporary schools have introduced additional symbols, either through channelings or personal adaptations, with the intention of broadening the possibilities of the practice.
How Many Reiki Symbols Exist?
The traditional Reiki system, known as Usui Reiki, is composed of four main symbols that are transmitted across different levels of training. Over time, a fifth symbol was added, which eventually became consolidated in many modern schools as part of the essential set.
In current practice, it is considered that the five essential symbols are: Cho Ku Rei, Sei He Ki, Hon Sha Ze Sho Nen, Dai Ko Myo, and Raku.
Beyond these five, various branches have added their own, derived, or complementary symbols, resulting in a wide range of approaches. Nevertheless, the symbols of Usui Reiki remain the most widely taught and used around the world, as they represent the original structure on which most Reiki systems are built.
The 5 Main Reiki Symbols And Their Function
In Usui Reiki, five symbols are used to represent essential aspects of the practice: power, harmony, distance healing, mastery, and energetic closure. Each one plays a specific role and is integrated at different points in the therapy to enhance energy flow, balance emotions, work with consciousness, and complete the healing process in an orderly way.
Cho Ku Rei is the symbol used to intensify and concentrate vital energy. It is applied to reinforce any treatment—whether physical, mental, or emotional—and is often used at the beginning of a session to increase Reiki’s strength. Its spiral shape acts as a channel that directs energy toward the area where greater intensity is needed, working as a force amplifier.
Beyond its role as an enhancer, it is also used to cleanse and protect spaces, as well as to seal the energy in the receiver at the end of the session. Thanks to its versatility, Cho Ku Rei is considered an indispensable resource that complements the action of the other symbols and provides safety and stability to every practice.
Sei He Ki is related to the balance between mind and emotions and is used when the goal is to release internal blockages that generate tension or discomfort. Its shape represents the union of the brain hemispheres and promotes integration between the rational and the intuitive, making it an effective tool to achieve states of calm and mental clarity.
This symbol is especially helpful in cases of anxiety, stress, or recurring thought patterns. It is also used to enhance memory, improve communication, and harmonize personal relationships. By balancing the inner planes, Sei He Ki allows energy to flow more freely, creating a state of holistic well-being.
Hon Sha Ze Sho Nen allows Reiki to be sent to people or situations regardless of physical distance or time. This makes it a key tool for distance healing, as it connects the practitioner with the recipient without the need for physical presence. Its energy is also used to work on past memories and experiences that still affect the present.
Likewise, this symbol is used to project energy toward future goals or situations, bringing clarity and balance to the path ahead. By transcending the barriers of space and time, Hon Sha Ze Sho Nen expands the reach of Reiki and opens the possibility of working in more subtle planes of existence.
Dai Ko Myo is considered the master symbol in Reiki and is associated with deep healing and spiritual connection. It acts on a high level of consciousness, allowing it to release deeply rooted patterns and support personal transformation processes. It is used both in therapeutic practice and in the initiation of new practitioners.
Its energy is primarily directed toward strengthening the spirit and integrating body, mind, and soul. Working with this symbol stimulates energetic regeneration and reinforces connection with one’s life purpose. For this reason, Dai Ko Myo is seen as a tool for inner expansion that fosters personal evolution and openness to a higher state of harmony.
Raku is the symbol used to conclude a Reiki session, as its main function is to seal and stabilize the energy received by the recipient. Its downward shape helps to anchor energy in the physical body, ensuring it remains grounded and does not dissipate after the session ends. In doing so, it brings a sense of completion and balance following the work done.
During initiations, Raku plays an important role in consolidating the energy transmitted from master to student. It also establishes a clear energetic boundary that protects both the practitioner and the recipient after the session. Thanks to this closing function, the Raku symbol ensures the integration of the therapeutic experience in a stable and organized way.
How Symbols Are Activated And Used In A Reiki Session
During a Reiki session, symbols are activated through the practitioner’s conscious intention. This can be done by visualizing the symbol in the mind, drawing it in the air with the hand, or mentally projecting it toward the area to be treated. What matters is not the precision of the drawing, but the connection established with the symbol’s purpose.
Once activated, the symbol integrates into the Reiki energy flow and directs the corresponding vibration to the specific body area, emotion, or situation being worked on. For example, some symbols are applied at the beginning of the session to enhance the energy, while others are used at specific moments to address emotional blocks or promote relaxation.
The use of symbols is not rigid—it depends on the practitioner’s preference and sensitivity. Several symbols can be used in combination during the same session, depending on the recipient’s needs. This gives flexibility to the treatment and allows the practice to be personalized for a deeper and more balanced effect.
Can Symbols Be Used Without Being Initiated Into Reiki?
In Reiki, initiation is a process in which a master transmits to the student the ability to channel and work with vital energy. In most courses and books, it is taught that without this step, symbols do not function as simple drawings that just anyone can use. According to this view, their effectiveness is linked to the initiation, which opens the conscious connection with energy through them. Without this activation, the symbols are considered to be only graphic representations without the same therapeutic strength.
However, some believe that anyone can benefit from meditating with the symbols, even without having received formal initiation. From this perspective, they are seen as forms that contain their own resonance field, capable of influencing the practitioner’s mind and emotions. While their impact may not be as deep as in traditional Reiki, they are still recognized as useful tools for finding calm and personal focus.
In truth, how their use is understood depends on the school, the teacher, and the practitioner’s experience. While some insist initiation is essential, others argue that the symbols are accessible to anyone who approaches them with respect and awareness. Both perspectives agree that they are not mere decorative drawings, but intention-charged expressions that can influence the inner experience of the one using them.
The Energy Behind The Symbols: Why Do They Work?
Reiki symbols work because they act as keys that allow access to specific energetic frequencies. Each one is designed to focus the practitioner’s intention and connect with a particular aspect of vital energy—whether to amplify, harmonize, or direct it remotely. This interaction between form, intention, and energy is what gives them effectiveness in therapeutic practice.
From an energetic perspective, symbols operate as patterns that organize and channel universal vibration. When used, the practitioner does not create the energy, but facilitates its flow toward a specific goal. This explains why combining the symbols with conscious intention can lead to perceptible effects on the body, mind, and emotions.
Their function can also be interpreted through more modern frameworks of understanding. Sciences that study energy and consciousness suggest that symbols work as bridges between the mind and the energetic reality around us. In this sense, they are not only spiritual tools but mechanisms of interaction with subtle fields still under exploration.
This principle can be related to contemporary approaches investigating the nature of energy and consciousness. In the series Quantum Effect, available on Gaia, Randy Veitenheimer explores how we live in a vast energy field and how consciousness influences our reality. His teachings offer a complementary vision that helps explain why tools like Reiki symbols can have an impact on our everyday experience.
