There are a number of major factors at work here:
1. Sympathetic Resonance
Sound Therapy instruments can help to restore our cells to their natural frequency, via sympathetic resonance.
This allows any area of imbalance to be harmonised through a like vibration.
By using the sound healing tools in close proximity to the area of imbalance, dissonant frequencies are transformed and original resonance can be restored.
2. Brainwave Entrainment
Sound waves affecting the brain also work through entrainment, which is when two oscillating waveforms gradually fall into phase.
This principle is universal and can be observed in many scientific systems: chemistry, neurology, biology, astronomy, etc.
Dutch scientist Christian Huygens first discovered the principle of entrainment in 1656. He placed two clocks with slightly different times side by side and found that they began to gradually synchronise.
This also applies to more complex structures such as the brain.
Brain wave entrainment relates to the brain’s electrical response to rhythmic sensory stimulation, such as pulses of sound.
When the brain is given an external stimulus, it emits an electrical charge in response: the 'Cortical Evoked Response'.
These are the electrical signals that travel throughout the brain and ultimately become empirical data: what we see, hear and feel.
3. Frequency Following Response
If the brain is presented with a repeating stimulus, it responds by synchronising these cycles to the same rhythm.
This is commonly called Frequency Following Response (FFR).
FFR is used in sound therapy to stimulate the brainwave frequencies that are associated with relaxation and positive well-being, since brainwaves are linked to states of consciousness.
When we create a range of sounds that induce the brainwave states associated with feelings such as peace, calm and healing, we can initiate and facilitate positive change.
For instance, when working with the 4-8 hertz 'theta' brainwave frequency, which is associated with both sleep and meditation, we can manifest these brainwave patterns to assist someone suffering from insomnia, stress, tension and anxiety.
FFR is also linked to the creation of many other states, including deep meditation, lucid dreaming and moments of peak realisation.
4. Balancing left / right brain hemispheres
Part of the process of the electrical reactions within the structures of the brain comes from the synchronisation of the two hemispheres of the brain.
The left-brain is linked to such principles as: reason, scientific proof and emotional objectivity.
The right-brain is linked with the principles of: creativity, intuition and empathy.
Through the use of sound healing instruments the two hemispheres of the brain can be balanced for optimum health, transformation and advancement.
All these factors are linked to another phenomena referred to as BINAURAL BEATS
