The current reference frequency for tuning musical instruments is 440 Hz. Some theorists and musicians claim that the 432 Hz tuning has better effects on the human body, but there are no scientific studies that support this hypothesis.
To identify differences in vital parameters and perceptions after listening to music at different frequencies, 440 Hz versus 432 Hz.
Cross-over pilot study.
A room dedicated to listening to music, in an Italian city.
33 volunteers, not suffering from acute and/or chronic diseases.
Two sessions of music listening on different days. Both sessions used the same music (movie soundtracks) but tuned to 440 Hz on one day and 432 Hz on the other. Each session consisted of 20 min’ listening.
Main outcome measures
Vital parameters (blood pressure, heart rate, respiratory rate, oxygen saturation), perceptions (physical and emotional sensations, for example fatigue and stress), levels of concentration during the listening session, and general satisfaction with the experience.
432 Hz tuned music was associated with a slight decrease of mean (systolic and diastolic) blood pressure values (although not significant), a marked decrease in the mean of heart rate (−4.79 bpm, p = 0.05) and a slight decrease of the mean respiratory rate values (1 r.a., p = 0.06), compared to 440 Hz. The subjects were more focused about listening to music and more generally satisfied after the sessions in which they listened to 432 Hz tuned music.
The data suggests that 432 Hz tuned music can decrease heart rate more than 440 Hz tuned music. The study results suggest repeating the experiment with a larger sample pool and introducing randomized controlled trials covering more clinical parameters.
We live in a sea of sound.
Even in silence, we can hear the beat of our own hearts. How often have you used sound to uplift your spirits when you are feeling sad or bad? Do you sing a song, play a CD, call a friend and talk? How often have you brought yourself and others down by words used in anger and frustration? Can the sounds we utter heal ourselves and others?
The sounds we hear around us affect our health and vitality. The Universe is made up of vibration and sound is not only a most potent tool in maintaining and creating our sense of well-being, but also can be used to heal the body, mind, and spirit.
Naad means “the essence of all sound,” the vibrational harmony of the Infinite. Naad Yoga is based on the experience of how sound vibrations affect the body, mind, and spirit through the movement of the tongue and mouth, and changes in the chemicals of the brain.
When we consciously regulate the sounds we make through the use of mantra, breath, and rhythm, we can produce profound effects on our health and well-being. The ability we have to affect our immune system through our thoughts and emotions has been scientifically documented. Mantra, rhythm, and breath used together can create a healing response in the immune system.
Psychoneuroimmunology is the study of the connection between the mind and emotions, and the endocrine, nervous, and immune systems. The link between these body systems and our sensations, thoughts, and emotions, is the limbic system which is made up of the hypothalamus, pituitary, and pineal glands. Sound, breath, and rhythm are intrepreted like a code by the hypothalamus.
There are eighty-four meridian points on the upper palate. With each stroke of the breath and the tongue striking the meridian points, it is like a beat of a baton that releases waves of neuro-chemical messages to activate the pituitary gland. The pituitary gland commands all the other glands, which in turn, regulate our immune function and emotions.
There is a special connection between the higher functions of the pineal gland and the use of the breath. When the breath is very slow (4 breaths per minute or less), a channel is opened by the hypothalamus between the pituitary and pineal glands. This releases an “inner nectar” or amrit that activates and accelerates the entire nervous system. Vitality and healing cascade through all levels of the mind and body. Nerves, muscles, and glands are at peak performance.
It’s as if mantra and breath are the conductors of a symphony and you are the composer. You can change the notes of the symphony, to create chords of happiness, sadness, vitality, or calmness. This capacity is inherent in our design and requires no special drug or belief. This process of creation exists because every one of our molecules is in communication with every cell and thought. The power of mantra uses sound, breath, and rhythm to command our mind, brain, emotions, body, and actions.
Excerpts from The Aquarian Teacher Level 1 Training Manual
Tune yourself to the heartbeat of our planet
To understand the healing power behind 432Hz, you must first learn about another frequency, 8Hz. It is said that 8Hz is the fundamental “beat” of the planet. The heartbeat of the Earth is better known as Schumann resonance and is named after physicist Winfried Otto Schumann, who documented it mathematically in 1952.
Schumann resonance is a global electromagnetic resonance, which has its origin in electrical discharges of lightning within the cavity existing between the Earth’s surface and the ionosphere. This cavity resonates with electromagnetic waves in the extremely low frequencies of approximately 7.86Hz – 8Hz.
The “ordinary” thought waves created by the human brain range from 14Hz to 40Hz. This range only includes certain types of dendrites belonging to brain cells, predominantly within the left (the more rational) hemisphere of the brain, which is the center of activity.
If the two hemispheres of our brain are synchronized with each other at 8Hz, they work more harmoniously and with a maximum flow of information. In other words, the frequency of 8Hz seems to be the key to the full and sovereign activation potential of our brain.
8Hz is also the frequency of the double helix in DNA replication. Melatonin and Pinoline work on the DNA, inducing an 8Hz signal to enable metosis and DNA replication. A form of body temperature superconductivity is evident in this process.
What 8Hz has to do with 432Hz tuning
432Hz resonates with the frequency of 8Hz
On the musical scale where A has a frequency of 440Hz, the note C is at about 261.656 Hz. On the other hand, if we take 8Hz as our starting point and work upwards by five octaves (i.e. by the seven notes in the scale five times), we reach a frequency of 256Hz in whose scale the note A has a frequency of 432Hz.
According to the harmonic principle by which any produced sound automatically resonates all the other multiples of that frequency, when we play C at 256 Hz, the C of all other octaves also begins to vibrate in “sympathy” and so, naturally, the frequency of 8Hz is also sounded. This is why (together with many other mathematical reasons) the musical pitch tuned to 432 oscillations per second is known as the “scientific tuning.”
This tuning was unanimously approved at the Congress of Italian musicians in 1881 and recommended by the physicists Joseph Sauveur and Felix Savart as well as by the Italian scientist Bartolomeo Grassi Landi.
In contrast, the frequency chosen in London in 1953 as the worldwide reference frequency and which all music today has been tuned to, has come to be defined as ‘disharmonic’ because it has no scientific relationship to the physical laws that govern our universe.
Natural healing with 432Hz
432Hz is the harmonic intonation of nature
According to the above information, playing and listening to music that has been tuned to 432Hz would make your body, and the organic world which surrounds it, resonate in a natural way. This would fill you with a sense of peace and well-being, regardless of the kind of song chosen to play or listen to.
Opening your ears for music that has been tuned to the “scientific” 432Hz frequency would benefit the entire planet and everyone who lives on it, while listening to music tuned to the “disharmonic” 440Hz frequency does harm by causing stress, negative behaviors and unstable emotions.
Listening to 432Hz music resonates inside your body, releases emotional blockages, and expands consciousness. 432Hz music allows you to tune into the knowledge of the universe around us in a more intuitive way.
