The History and Science Behind Solfeggio Frequencies

Solfeggio frequencies are specific tones of sound that help with and promote certain aspects of mind-body health.

The use of these frequencies for healing purposes dates back to ancient history. These tones are said to be the fundamental sounds used in both Western Christianity and Eastern Indian religions. They’ve been chanted by Gregorian Monks and have also been used in ancient Indian Sanskrit chants.

It was in the 1970s that the Physician and researcher, Dr. Joseph Puleo, rediscovered Solfeggio frequencies and brought their benefits back into public awareness. In his research, he used mathematical numeral reduction to identify six measurable tones that bring the body back into harmony and aid in healing various ailments.

Solfeggio frequencies are known to profoundly affect the conscious and subconscious mind by stimulating healing and vitality. Thanks to Puleo’s work and the renewed interest, many scientists have since unearthed more evidence supporting the positive effects of these holy tones on the human body.

In 1988, biochemist Dr. Glen Rein made a huge discovery testing the impact of different music on human DNA. He confirmed what the ancient spiritual traditions had already understood: Sounds can have an altering effect on our DNA! The Gregorian and Sanskrit chants had the most positive, yes even healing effects on human DNA!

Since Rein’s illuminating discovery, further research has shown that Solfeggio frequencies have a powerful effect on people’s mental, emotional and physical states. 

The Specific Frequencies and their Benefits

432 Hz – deeply calming and soothing

Many ancient musical instruments were constructed for 432 Hz tuning and before the mid-20th century, 432 Hz was the standard of instrumental tuning. Since then 440 Hz tuning has become the norm. The 432 Hz frequency resonates with the Schumann Resonance of 8 Hz and is known for its deeply calming and soothing effects. A double-blind study from Italy showed that music tuned down to 432 Hz slows down the heart rate when compared to 440 Hz. This frequency fills the mind with feelings of peace and well-being.

528 Hz – healing and repairing

The science on the reparative effects of the 528 Hz is still in its infancy, but research indicates that it has the ability to heal and repair the body.

A 2018 study from Japan discovered that music tuned to the frequency of 528 Hz significantly reduced stress in the endocrine systems and autonomic nervous systems— and this even after a mere five minutes of listening!!! How is that??? And in a study published in the Journal of Addiction Research & Therapy, the frequency of 528 Hz reduced the toxic effects of ethanol on cells, the main ingredient found in alcoholic drinks. Plus: this frequency also increased cell life by about 20 percent!

396 Hz – combat fear, worries & anxiety

Music tuned to 396 Hz helps remove subconscious fears, worries, and anxiety. It also helps to eliminate feelings of guilt and subconscious negative beliefs that keep you from achieving your personal and professional goals.

639 Hz – harmony in relationships 

The frequency of 639 Hz helps balance emotions and elevates mood. It also promotes communication, love, and understanding, and brings harmony into interpersonal relationships.

741 Hz – awaken intuition

Music tuned to the frequency of 741 Hz helps with problem-solving, cleansing the body, and self-expression. It also helps to awaken intuition and promotes living simply and purely. This frequency is ideal if you’re struggling with living a healthy lifestyle, expressing creativity, or speaking your truth.

The 852 Hz frequency helps to replace negative thoughts with positive ones, making it ideal when nervousness or anxiety is bringing you down. It also aids in awakening intuition and inner strength.

Additionally to these 6 frequencies I also use the 136.1 OM Frequency (my clients’ favorite sound) – the tone of our Mother Earth – to help you feel safe and grounded and trust in this life and beyond.
