The  Nada Yoga, the yoga of sound, is an aspect of yoga that uses sound, mantras and music in order to reach the goal of Yoga: a harmonious integration of body, mind and spirit. To achieve this goal, yoga has many psychophysical techniques, including those of Nada Yoga.

Recently, a contemporary master, Vemu Mukunda, a nuclear physicist and famous Indian musician, developed it by drawing on the ancient traditions of the Vedas, the Indian sacred texts. Combining his scientific studies with the millenary tradition of his country, he elaborated a long investigation on the human body and its physical and psychic responses to sound, arriving at the conclusion that every living being is a sound. His scientific training in nuclear physics has allowed him to develop the aptitude to experimentally verify everything that the millenary Indian musical tradition has handed down to us. His therapeutic method uses sound as a vibratory phenomenon that can act directly on specific points of the body. These points are connected to emotional states, therefore, sound used carefully can induce both psychic and physical changes in the desired direction.

The possibility of inducing transformations in the field of matter makes this method very different from the modern music therapy of the Western world which instead uses music mainly as an instrument of communication, play and socialization. Hence the need to return to the source, to Shabda Brahma, the Creator Sound, with the help of Nada Yoga. The basic principle of Nada Brahma Yoga, described in the Vedic texts, states that first it is necessary to purify the mind by bringing it back under control, then regulate the sensory perceptions to have a more harmonious life. Subsequently it is possible to radiate sound vibrations and use specific passages and certain musical movements to allow the patient to heal himself, helping the self-regulation of the various systems of the organism.

Voice, notes and scales of emotions

Every human being, says Mukunda, when he reaches adulthood takes on a vibration that distinguishes him and makes him a unique and characteristic note of the great cosmic concert. Finding out what your personal note is (Tonic or Ground Tone) and how it vibrates inside the body that acts as a sound box, helps to re-harmonize the energies to feel better in your body, in the places and with the people with whom you live in all areas, as a couple, in the family, at work. But discovering one's personal or fundamental note also means going to the root of the personality, discovering its dark and surprising sides. In fact, in addition to words, the voice hides deep resonances of what we are when we really are ourselves. And like the body, the voice also sends messages that go beyond words. Just think of the intonation alone: broken, broken, trembling, it indicates anxiety or worry, while a relaxed, calm or lively tone conveys security, inner calm or joy.

By studying the data relating to the frequencies traveled by a person's voice while speaking, it is possible to observe that it always tends to speak around a certain frequency. It is observed that the tone of the voice forms a sort of melody, repeatedly crossing certain notes, and that each individual tends to repeat a certain melodic path and to repeatedly cross certain frequencies. Finally, we note that a particular note emerges and stands out as a central element. So a person speaks and sings based on a certain frequency which tends to remain constant. A change in this fundamental note occurs when we are in the presence of strong emotions or mental agitation. The fundamental note corresponds to the navel chakra and expresses the general characteristics of the person.

Master H. Mitra states: "The fundamental note of a person represents in the form of sound the umbilical cord that connects him to existence. It defines what is fundamental, indispensable, essential in his life"

The voice is therefore a spy of emotional states which, again according to Mukunda, can be precisely placed in the chakras, the energy centers ideally placed along the spine, from the coccyx to the center of the head. Each chakra vibrates at an ever higher frequency as it rises from the base of the column to the top of the head and behaves a bit like the strings of a guitar or double bass. The darkest and deepest notes come from the string that vibrates more slowly, the higher ones from the string that vibrates faster.

In practice, how is personality analysis done with the yoga of sound? The search for the personal note is done through individual meetings in an environment that is as natural and relaxed as possible. The person is asked to be silent for at least 20-30 minutes before the session, to promote concentration. Then, sitting comfortably in front of the teacher, the person concerned begins to talk about everything that passes through her mind while a frequency meter (FFT) detects the frequencies of the voice.  Within half an hour, at most 45 minutes, the dominant note can be identified and a picture of the personality can be made. However, this research work is not as immediate and easy as it might seem, because disturbing elements can intervene, for example imbalances in the flow of the person's energy that prevent, divert or make it difficult to identify the personal note. Since this represents a moment of inner growth it must be guided, therefore any do-it-yourself attempt is not recommended.

The voice changes in relation to the different experiences of the moment and its frequencies also change. Normally the frequency of a voice conditioned by the various moods has the extension of a musical octave. This is the middle octave of a series of three resonant octaves that we can find in the human body: lower octave from the big toes to the navel, middle octave from the navel to the center of the forehead (spiritual eye) and upper octave, from the spiritual eye at the top of the head. In the central octave the lower tonic produces mental and physical calm and is located at the navel. The upper tonic brings spiritual serenity and recalls awareness in correspondence with the spiritual eye, in the center of the forehead, where the crossed eyes ideally look upwards. All other emotions lie between these two points and the frequency of the voice changes as awareness moves from one point of the body to another. Ascending from the lower tonic to the upper one, along the sound spectrum of an octave, you will pass through 22 main points of emotional energy, called Nadi, which correspond to as many points in the body, and awareness will move from one emotion to another .

All created things, from the grossest phenomena to the most subtle phenomena, such as thought, are in a state of perpetual motion and everything that is in motion emits vibrations, therefore sounds. In the human being the voice is the channel through which the conscience manifests itself externally; it is the link between the mind and emotions of one person to those of another. All things that vibrate are sensitive to each other, so we could say that sound is the link between all phenomena. Just as the strings of a guitar that are plucked vibrate and cause the soundboard or the strings of another instrument to vibrate, so too all things influence each other through the subtle law of vibratory exchange. According to the ancient teachings of India, the most perfect of all instruments is the human voice. No other instrument expresses the nuances of thought and feeling so perfectly. The change in the most delicate mood directly affects the voice: the sharp knife of anger, the bubbling cadence of laughter, the miserable and hard tone of greed, the sweetness of compassion. Words, rather than pure sound, are the spirit of the individual manifested on a material level of existence. When words are used righteously as a conscious expression of the spirit, they have the power to reach the heart of everything, to perform what ordinary people refer to as "miracles".

Certain vibrations of thought and feeling, although imperceptible on a sensory level, can be picked up in some way, since they react on several levels. These vibrations combined with music, which in turn is saturated with the power of thought, can influence Nature in all its aspects. All objective music is based on the "inner octaves". It can give precise results, not only of a psychological nature, but also of a physical one. There is such music as to freeze the waters, just as there is music capable of killing a man instantly. The legend of the destruction of the walls of Jericho with music is indeed a legend of objective music. The legend of Orpheus is woven on such memories because Orpheus used music to teach. The music of the snake charmers in the East is another example. Often it is only a single note, just modulated and indefinitely prolonged; in this simple note, "inner octaves" are incessantly developed and, in these octaves, melodies that cannot be perceived by the ears, but which can be heard in the emotional center. And the snake hears this music or, better said, hears it and obeys it.

Voice is the primary means of transforming our thoughts, sounds, emotions and feelings into physical form in the material world. It is also a means of identifying the person. The voice is part of our personality. Understanding the voice and its variations is very important and can help to have self-awareness and understanding of how emotions "move".

The professor. Marco Ferrini talks about the transforming power of the word and its relationship with the sacred:

"Instrumental musicality is inferior to that of speech. Truth is music in itself, it is the transforming divine music, which transforms the environment and people. Great leaders of humanity have transformed entire masses with stories and parables, metaphors . Today music is consumed, it is not used as a transcendental medium in the Kantian sense, but as one of the many disposable objects, therefore it has become desecrated, become subject to fashion, garbage stuff. Who produces it has abused music. , making it an object of consumption. Music was used to accompany a sacred act, to transform into sacred what was not sacred. It was used as a spaceship to go to other dimensions, to other levels of reality. Now the attitude and the attitudes are very different and it is evident that they lead to different results. Modern man theorizes music in a distracted way, while doing other things, the music is therefore a surplus. It is like putting on perfume trivially and not. instead to go to the wedding, to the stake or for a solemn oath. Today music is used to narcotize, stun, induce, hypnotize. Sounds are always in the air, as colors are always available on the palette, but the artist who makes celestial music with those sounds helps us to transcend and send us back to other worlds, to the essential joy that does not depend on the outside. but it naturally springs from our heart ".

The ancient Sanskrit term "Nada" indicates that sound originates from the union between the energy of the breath (na) and that of heat (da) and it is precisely the friction of the breath against the vocal cords that causes the voice to spring. . The first effect is in fact in the use of vocal systems and techniques to activate an action of the breath on the vital energy, Prana. The second effect is that of the activation of the element of heat, which in the Vedas is associated with consciousness (Cit-Agni). The sound is therefore able to evoke this energy, the heat perceived during singing is an indicator of this activation. In the case of "held" emotions we are faced with frozen energy, crystallized, as it is deprived of its dynamic force, and which must be dissolved and processed. We know that talking about your problems already helps to unfreeze these blocked energies and consequently the associated feelings and emotions.

Emotions are comparable to waves as they are dynamic energy activated by the contact and confrontation between the individual and reality, and as with waves, they cannot be stopped or suppressed but only transformed, if necessary. The voice and the breath can be powerful tools of transformation, freeing the channels of vital energy from internal toxins which, in addition to conditioning and polluting the mind, can also create negative consequences on a physical level. When the inner conflict is resolved, the restored harmony is reflected on the mental and emotional level, allowing access to the higher planes of being.

The process leading to the higher planes of the spirit must first harmonize the emotional and mental planes and anything else that can agitate the psyche. This is why chants and sacred music often have healing properties.

In the Vedic tradition it is said that "a pure mind becomes a messenger of the gods", and the winged horse of "divine messages" is intuition, which however needs to find the path free from emotional blocks in order to reach the mind.
