What Is Biofield Tuning?

A Sound-Based Practice for Restoring Coherence & Balance

Biofield Tuning is a sound-based practice developed by Eileen Day McKusick that uses tuning forks to support relaxation, awareness, and energetic balance across the physical, mental, emotional, and subtle body systems.

Rather than “fixing” or forcing change, Biofield Tuning works by introducing coherent sound into areas of energetic tension or dissonance—allowing the body’s own intelligence to reorganize toward greater harmony.

Understanding the Biofield

The Body Is More Than Physical Matter

The term biofield was introduced by the National Institutes of Health (NIH) to describe the complex field of energy and information that surrounds and interpenetrates living systems. As experienced and mapped through Biofield Tuning, the biofield can hold:

  • Emotional experiences
  • Memory patterns
  • Stress responses
  • Stored energetic charge from stress or traumatic experiences

These patterns don’t live only in the mind—they register as vibrational information in the field around the body.

What “Tuning” Really Means

Listening Before Anything Changes

“Tuning” refers to using the coherent frequency of tuning forks to read and interact with the information present in the biofield.

The forks act as a feedback tool, helping locate areas of incoherence or resistance. Simply bringing attention and sound to these areas can allow stored energy to soften, reorganize, or release—often without force or analysis.

Coherence vs. Dissonance – How Balance Is Experienced

  • Health & ease are associated with coherence, resonance, and flow
  • Stress & stagnation often appear as dissonance or energetic resistance


Biofield Tuning does not diagnose or treat conditions. Instead, it creates an environment where the system can naturally move toward greater coherence.

Trauma as Stored Energy

When Experience Leaves a Vibrational Imprint

Emotional experiences can become stored as energetic charge in the biofield.

Sometimes, simply observing these areas with sound, attention, and neutrality is enough to initiate change. The process is often subtle, gentle, and deeply personal.

Why Sound Works – Sound Is Not Abstract — It’s Physical

Sound is a mechanical wave that moves through matter. It interacts directly with: Tissue, Water, The nervous system, The electromagnetic field of the body

Sound provides immediate feedback and can help reorganize disordered systems—something demonstrated clearly in cymatics, where sound visibly shapes matter.

Frequency, Amplitude & Information

How Sound Communicates With the Body

Frequency (Hz): The pitch of sound — carries information
Amplitude (dB): The strength or loudness — affects depth of impact

In the biofield, frequency acts as informational input, not force.

Resonance & Entrainment

The Core Mechanism of Biofield Tuning

Resonance occurs when a system responds to a frequency that matches it. Entrainment is what happens when a less organized system naturally syncs with a more coherent one.

Tuning forks emit stable, coherent vibration, encouraging dissonant areas of the field to reorganize—much like how slow breathing can calm heart rate and brain waves.

The Tools Used in Biofield Tuning

Simple Instruments, Precise Feedback

Weighted tuning forks: Applied gently on the body for grounding, physical tension, and somatic awareness

Unweighted tuning forks: Used in the biofield to locate and interact with energetic patterns

These tools don’t impose change—they offer order, allowing the system to respond.

The Role of Intention

Consciousness Shapes the Experience

As sound healing researcher Jonathan Goldman notes:
Frequency + Intent = Healing
Intent is the consciousness behind the sound.

The practitioner’s role is to remain neutral, present, and attentive.
Creating a safe space for awareness and coherence to emerge.

What to Expect in a Session

A Calm, Observational Experience

  • The practitioner listens and responds to the biofield
  • Nothing is interpreted, diagnosed, or “fixed”
  • You are invited to relax, remain curious, and notice subtle shifts


Each experience is unique and unfolds at its own pace.
