  • What happens during a Biofield Tuning session?
    This answer pertains to what happens during an in-person Biofield Tuning session (when the practitioner and client are in the same room). To learn about what happens during an audio session or a group audio session, please visit the Audio & Distance Sessions cagtegory at the top of this page. During an in-person Biofield Tuning session, the client lies fully clothed, face up, on a treatment table (much like a massage table) while the Biofield Tuning practitioner applies the handles of vibrating tuning forks to specific points on the client's body. The practitioner also slowly moves tuning forks over the recipient's body. Clients will feel the difference in the vibration of the tuning forks depending on which spot is being touched. They will also hear how the sound of the tuning fork changes depending on where the fork is held over the body. The practitioner works towards the body starting from about 5-6 feet away, listening for "noise" in the "signal" and feeling for a sense of resistance. When they encounter an area of perturbation, they pause. The introduction of the coherent frequency of the tuning fork into a client's area of incoherence causes the body to “auto-tune” itself, resulting in a resolution of the "noise" and a releasing of the resistance held in relationship to it. The resistance or charge that was held in that particular area is then dissolved and "swept back" into circulation. The simple action of treating areas of dissonance in a client's energy field creates targeted and immediate relaxation that can bring resolution to a wide variety of ailments.
  • How many sessions do I need to experience before I can expect to receive benefits from Biofield Tuning?
    Biofield Tuning is cumulative; every session builds on the one prior to it. Like chiropractic trains the bones to find their balanced relationship, Biofield Tuning trains the magnetic/electric system of the body to flow in a balanced, rhythmically harmonious way. If a person has had long-term, extreme, non-beneficial inputs, it will take longer to achieve balance. Younger people respond more quickly than older people. Generally, a minimum of three sessions is recommended to begin. Often, a presenting symptom can be cleared within three sessions. If there is no change in a condition after three sessions then it is likely that Biofield Tuning will not be able to help with that particular condition.
  • Is there an age limit for receiving Biofield Tuning?
    There are no age limits for receiving Biofield Tuning, however less is more with both seniors and children, who generally should receive shorter sessions. Children between the ages of 2-6 can become very hyperactive after Biofield Tuning sessions.
  • Can Biofield Tuning treat conditions like Parkinson’s, multiple sclerosis & diabetes?"
    Many Biofield Tuning Practitioners have reported that clients with conditions such as Parkinson's, MS and diabetes have experienced relief in symptoms via Biofield Tuning treatments. Please note, although Biofield Tuning can work well for these conditions, please read our Cautions and Guidance category at the top of this page if you have active cancer, are pregnant, are terminally ill or have an implanted electronic device.
  • Can Biofield Tuning treat issues like depression or bipolar disorder?
    Yes. We view conditions such as depression and/or bipolar disorders as "tonal" imbalances rather than chemical imbalances, which can be readily addressed with Biofield Tuning. For example, during a Biofield Tuning scan a bipolar person will exhibit "high tones" associated with anxiety and mania, as well as "low tones" linked with depression, but a "mid-tone" range will be absent. In such cases, the Practitioner uses Biofield Tuning to quiet the high tones and lift the low tones which in turn will strengthen the mid-tone range. This helps the recipient achieve a more balanced state.
  • Does Biofield Tuning work on animals?
    Animals respond beautifully to Biofield Tuning. Biofield Tuning has helped pets stop being fearful of thunder, more trusting of strangers, stop fussing with hotspots, and generally enter a healthier, relaxed state. Pets respond well to in-person Biofield Tuning and also when they receive Biofield Tuning from a distance (aka known as "distance work").
  • What is Biofield Tuning detox?
    Biofield Tuning recipients may experience a "detox response" after a session. This is completely normal and means the body is releasing stress and trauma. Generally, these symptoms pass within 1-3 days. The following are possible symptoms of detox: Fatigue Waves of emotions – crying, being angry, sad Loose stools Exhaustion Headaches and/or dizziness Flu-like symptoms In very rare instances - skin rashes, mucus, fevers, vomiting, excessive thirst If you are having a detox response from your Biofield Tuning session - especially if it is an extreme response - we highly recommend that you contact your Practitioner. They will be able to support you through your detox and schedule another session to help move it through.

  • What is the difference between Acutonics & Biofield Tuning
    Acutonics® is a system of vibrational sound healing that uses tuning forks the body's grid system of acupuncture points and meridians. The tuning forks are used on and off the body. Rooted in Oriental medicine and philosophy, Acutonics is unique in its use of: tuning forks tuned to planetary frequencies combining two forks to create a musical intervas planetary archetypes To learn more about Biofield Tuning click here.
  • What are the Schumann resonances? Are they increasing and if so how does that affect your forks that are based in the 7.83 Hz frequency?
    The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere. While a variety of sources report that the Schumann resonances are increasing, this information does not impact the effectiveness or usefulness of our forks that are based on the 7.83 Hz average of this background pulse of electrical activity within the earth’s ionosphere. In order for this fundamental frequency to increase, the distance between the earth’s surface and the inner boundary of the ionosphere would have to be decreasing. There is no evidence this is happening. What appears to be going on based on the limited amount of information available, is that the amplitude or the strength of the signal has been fluctuating, causing the higher harmonics of this frequency to be more strongly accented. The fundamental remains the same. We have perceived no difference in the way the body receives these frequencies despite the fluctuation of the signal.
  • What is a distance Biofield Tuning session?
    A distance Biofield Tuning session is when a Biofield Tuning Practitioner works with a client or clients who are not in the same room with the practitioner. The distance between the Practitioner and the receiver does not matter.
  • What is audio Biofield Tuning?
    Audio Biofield Tuning is much like a distance Biofield Tuning session except instead of working with a Practitioner in real time, the recipient is listening to a pre-recorded session targeted to a specific area and/or concern. Audio sessions may be listened to at your leisure. To learn more about audio Biofield Tuning sessions click here.
  • What can I expect from a one-on-one distance session?
    During a one-on-one distance session a client reclines comfortably at home and connects with the practitioner via phone or Skype. The session is conducted in the same manner as if both people were in the same room. The practitioner is able to find the same patterns of feedback variation as they move through the field around the recipient's body from a distance as if they were actually there. Some practitioners may work without a live connection, but rather with intention and then connect with the client afterwards to discuss the session. Note: Biofield Tuning cannot be practiced at a distance on someone who has not agreed to receive the work.
  • What can I expect from a group distance session?
    In a group distance session, participants connect by phone or internet to listen to a one hour audio broadcast of a Certified Practitioner working within the “collective energetic field.” The Practitioner works within the field of “everyone present on the live call and anyone who will listen to the call in the future.” The work is a combination of education, coaching and deep energetic shifting. 75% of survey respondents say they experienced a sense of energy moving in their bodies during these sessions. (Please note: the session is still working even if you do not have a visceral sense of energy moving through your body). Participants of multiple sessions report feeling more resilient, clear, grounded, lighter and a experiencing a wide variety of diminished symptoms. Recordings of previous sessions can be accessed here. Recordings of sessions can be listened to as many times as one would like.
  • How are Biofield Tuning audio & distance sessions even possible?
    Had we not conducted numerous experiments testing the viable effects of audio and distance Biofield Tuning sessons with astonishing reports of clients experiencing significant state changes, we would not believe it ourselves. Biofield Tuning founder Eileen McKusick scoffed at the idea of practicing Biofield Tuning from a distance until she was persuaded by Dr. Karl Maret to test its effects. Their first distance session was performed via speaker phone. Dr. Maret rested on a treatment table in California while Eileen stood at her table in Vermont. She approached the table with her tuning forks as if Dr. Maret were on the table in front of her and much to her amazement, she encountered patterns of changing tones, resistance and distortion. Dr. Maret reported feeling energy shifting in his body during the session, and after he reported feeling different and relief from symptoms. Based on this test session, Eileen decided to conduct a series of experiments testing the legitimacy of distance sessions. Her experiments showed that the information present in the electromagnetic field is consistent and predictable regardless of distance. The same pattern of information storage in the biofield anatomy repeats in everyone; the frequency signatures of each emotion, each ailment are the same (at least as far as Eileen has been able to determine so far). To learn more about this phenomenon, please see our FAQ question "What is the aether".
  • What is the aether?
    One of the biggest omissions in our collective cosmology or understanding of the nature of life is "aether". Essentially luminiferous, aether is the ocean of clear light that all of creation arises from. Information travels through this medium much faster than light speed because the information of the entire field is accessible at any point. While the term "aether" is not in our popular lexicon, the concept of the phenomenon persists, and has been referred to by many other names including "the zero-point field," "the source field," "the torsion field," "the field," "the Akashic field," and even "the Higg’s field," whose definition, “an invisible energy field that exists throughout the universe,” is very similar to the definition of aether. This can potentially explain the mechanics of how distance healing works. With your intention, transfer your awareness from your left foot and then into your right hand. Notice that there is no sense of that awareness having to travel in a linear way through your body. In this same way, a client can place their intention, their awareness and their consciousness on a treatment table, regardless of where it is in actuality. It is through this same kind of intention that vibrational patterns can be found at a distance with a Biofield Tuning Practitioner’s tuning fork and modulated into a more coherent and harmonic expression. As the non-local interconnective medium that unifies us all in real time, aether is the missing link in so-called paranormal phenomena such as remote viewing and distance healing.

By sharing this information, BioSona, LLC does not accept responsibility for any possible outcomes.
  • Can Biofield Tuning be used on those nearing the end of life?
    Biofield Tuning may overwhelm end-of-life body systems which are often in a depleted energetic state. End-of-life detox may be uncomfortable as the body may not have the resources to effectively manage detox symptoms. Components of Biofield Tuning have been used as a means of calming the nervous system during end-of-life circumstances to ease transition.
  • Should I use Biofield Tuning if I have cancer?
    Once cancer has advanced in the body, detox pathways are often compromised, and the body may have difficulty digesting newly introduced energetic input. The body may not have the resources to effectively manage detox symptoms that may result from Biofield Tuning. We have observed tumors may be irritated by tuning and as such, we suggest not applying forks directly on them. These statements refer to cancer that is active and/or in treatment; not to cancer that is in remission
  • Should I use Biofield Tuning if I am pregnant?
    During pregnancy, the body expends a tremendous amount of energy; Biofield Tuning may overwhelm this already overextended system. The body may not have the resources to effectively manage detox systems which may affect both mother and baby. Components of Biofield Tuning, such as using weighted forks on the body for limited duration, have been used to promote relaxation during pregnancy.
  • Can Biofield Tuning be used with pacemakers & electrical medical implants?
    Tuning forks may interfere with the electrical functioning of these devices due to the added vibrational input. No reports of ill effects have been associated with newer pacemakers. Proceed with caution, careful observation, and the advice of your medical professional. Electrical medical implants also include, but are not limited to Medtronic pumps and neural implants.
  • Can Biofield Tuning be used if I have a concussion?
    When the brain is swollen, it takes time for inflammation to resolve. We suggest waiting at least 3 months after a significant injury for the brain to heal before receiving Biofield Tuning on or around the head. The rest of the body can receive gentle tuning shortly after injury occurs. Each case is different – with mild concussions, components of Biofield Tuning may be used before the 3-month waiting period.
  • Can Biofield Tuning be used on those who are morbidly obese?
    Suppressed emotions and energy can be held in adipose tissue. If there is extensive adipose tissue, Biofield Tuning may result in unpredictable and strong emotional releases and/or uncomfortable detox responses. Individuals may be more comfortable receiving Biofield Tuning while seated versus on a treatment table.
  • Is Biofield Tuning contraindicated for those with metal toxicity?
    A Biofield Tuning session may initiate a large release of toxins from cells, resulting in discomfort. Some individuals with heavy metal toxicity have experienced a strong detox response following a Biofield Tuning session. Consider seeking guidance for supplements that may support the detoxification process.
  • Can Biofield Tuning be used on varicose veins?
    Avoid using firm pressure with weighted forks directly over large varicose veins. This has the potential to dislodge blood clots. Consider working gently with mild pressure in the area around varicose veins rather than directly on them. No reports of ill effects have been associated with using gentle pressure on and around spider veins.
  • Can Biofield Tuning be used on dental anomalies?
    Avoid using direct pressure with weighted forks over dental implants, chipped/broken teeth, or bone fragments in the gums, as this may cause them to shift due to the vibration of the tuning fork.
  • Should Biofield Tuning be used on fractured bones?
    Avoid working with weighted forks directly on any recent broken or fractured bones, as the vibrational input can be uncomfortable and interfere with the natural healing process.
  • Should I use Biofield Tuning if I have metal implants?
    Direct pressure with weighted forks on these areas may cause discomfort. In these circumstances, consider gentle use of the tuning forks until you gain a sense of how your body responds. Implants include, but are not limited to; metal rods, screws and plates.
  • Are Biofield Tuning Group Audio Distance Sessions safe?
    In the five years that Group Audio Distance Sessions have been conducted, thousands of people have received them and very few adverse reactions have been reported.

    The Sonic Slider is a unique tuning fork that harnesses the power of therapeutic sound to help you feel and look younger and healthier. Users report a wide range of benefits from using the Sonic Slider for 10 minutes a day or less, including more energy, greater well being, reduced cellulite, weight loss, increased muscle tone, smoother skin, reduced pain, improved circulation, less fluid retention, and more. No batteries, chemicals or subscriptions are required - just an easy to activate tuning fork with a unique frequency that is easy to learn how to use and can produce quick, noticeable changes in how you look and feel. To see more information please visit:
  • What is the frequency of the Sonic Slider & why does that matter?
    The Sonic Slider's frequency is 93.96 Hz 93.96 Hz is the 12th harmonic of the Schumann Resonance - the electromagnetic resonance of our atmosphere - which is (on average) 7.83 Hz. 7.83 x 12 = 93.96 Hz. Eileen's research with tuning forks based in the Schumann Resonance has shown her that the human body responds favorably to this frequency and its overtones. Over the years, she has created many prototypes based in the Schumann Resonance as well as other systems, and she knew right away that this particular prototype had special qualities.
