A Western Therapeutic Perspective

Overtone singing is an ancient technique that enables a singer to produce 2 or more sounds simultaneously with his or her voice. Although the origins of this technique are partly cloaked in mystery, recent investigations have unturned an enormous amount of information regarding the present uses of the technique and some information regarding its origins in different parts of the world.

Origins of Overtone singing

2014-health with musicOvertone singing as a technique and cultural or spiritual musical artform, developed in Mongolia , Southern Siberia and Central Asia, in Tibet , and in South Africa . It also is used to a lesser degree in Sardinia , the only ancient form of European overtone singing that is still practised. Many theories exist that overtone singing once had a ritual and spiritual use in Kabbalistic ceremonies, Masonic lodges, mystery schools and Sufi practices. Some theories go as far as to say that it was used as long ago as the civilizations of Atlantis, Ancient Egypt and Mayan Central America. Unfortunately there is scanty information in this regard.

Overtones, known also as harmonics, were first discovered in the West by Pythagoras some 2 600 years ago. The famous Greek philosopher and mathematician was also a musician, and together with his students spent years studying sound and vibration. He found, after studying the monochord, a single stringed instrument, that all sounds were composed of multiple vibrations or frequencies, not just one, as our ears generally perceive.

How does Overtone Singing works ?

Our brain can tell immediately whether a certain note has been played by a flute, a guitar or a piano. If the overtones are filtered out, we become unable to distinguish between these instruments.

Just as the rainbow is made up of the colours that the human eye sees as white light, overtones (harmonics) are the colours of sound. These overtones, which usually go unnoticed, are actually vitally important for all human beings, and allow us to differentiate between one sound and another. It is the richness of the overtones in certain parts of the infinite spectrum of sound which help us to tell the difference between one musical instrument and another, even when they both play the same musical note.

The human voice is the musical instrument richest in overtones, due to our ability to make the tiniest of adjustments at will, thus fine-tuning the voice beyond the capacity of most musical instruments.

Most music students and musicians learn about the theory of overtones, and some are even able to produce overtones with their instruments. The guitar will produce overtones when the strings are strummed while the finger of the other hand dampens the strings along one of the frets. A flute, saxophone or other wind instrument will often produce an overtone when over-blown, that is, when too much air pressure is applied, the sound will jump a whole octave higher. The bass guitar is perhaps the best-known producer of overtones in modern music. Jaco Pastorius, who played bass for avant-garde jazz group Weather Report, played whole melodies using just the high-pitched harmonics of his bass, as in the song “Portrait of Tracy”.

It is the overtones of the human voice, however, that are the most interesting, magical and mystical to hear. The singer produces a single, powerful humming sound, and then, through a variety of techniques, converts his whole upper body into a vibrating resonance chamber. Using the cranium, nasal passages, pharynx, chest, abdomen, and diaphragm, as well as all the parts of the mouth: tongue, lips, palate, soft palate, glottis and epiglottis, cheeks and jaw, the singer begins to channel the sound differently to a singer in the more “normal” singing traditions.

The sound that follows must be heard to be believed, in fact, many people do not at first believe what they are hearing, as a clear, beautiful, flute-like sound appears above the voice of the singer. An accomplished overtone singer is able to sing up and down the Harmonic Scale (Overtone Scale), reaching, in the case of a singer with a deep voice, up to 16 overtones or more. These overtones follow a fixed arithmetic sequence, and always conform to the same principle. If the singer sings a note with the frequency of 100Hz (cycles per second) then the first overtone will vibrate at 200Hz, the second at 300Hz, the third at 400Hz etc. This is what Pythagoras discovered when dividing the string of his monochord into equal parts. The overtone scale within each musical note is infinite, although we can hear and produce audibly only the first 5 octaves or so, and this only in the case of an adept overtone singer.

Once one has learned to follow the sets of mouth movements, and produce a good strong hum, the rest is re
ally quite easy. Most people can learn to sing some overtones in just a few hours, but some practice is needed to begin to hear your own overtones, and then slowly to increase their volume.

Once one has mastered the scale and is able to sing both up and down the Overtone series, the next step is to be able to select the overtone of your choice, so that a melody can be composed or improvised. Most people can do this within a few months of learning the technique, although I have taught many people who were able to improvise in just a few weeks. It depends on how much one practises.
Once one has mastered singing the scale and improvising (in much the same way as many people who whistle improvised tunes, made up as they go along), the next level of overtone singing, practised mainly in the West, involves changing the fundamental pitch of the voice, rather than holding one single drone.

A singer is thus able to create one melody line with the voice, and a second, flute-like melody above the voice, in essence a self-accompaniment. Indian “ragas” and Gregorian Chants are musical forms that easily lend themselves to this style of Overtone singing. While this is to be admired as an accomplishment attained by very few people, it can also serve to lose the deeply meditative and spiritual effect of the music. It is necessarily more a mental and intellectual exercise, requiring intense concentration, and the resulting music can be robbed of its essential trancelike effect. It is also extremely difficult to sing from the heart when everything has to pass first through the intellect.

One of the most healing, meditational and spiritual aspects of overtone singing is the funda
mental drone ; the unchanging groundnote or rootnote from which the overtones spring. An unchanging drone is the basis of most Indian music, and certain instruments have been designed in India and used for millennia for this purpose, such as the simple harmonium or “shruti box” and the Tampura. A fundamental drone is also the basis for Mongolian overtone singing (called khöömii) and most other forms of overtone singing. Other drone instruments rich in overtones are the didgeridoo of the Australian Aborigines, the mouth-harp (Jew’s harp or guimbarde),
the overtone mouthbow (known as the berimbao in South America, and as the Uhadi or Umrubhe in Southern Africa , where it originated).

It is important for us to realize that while overtones represent the natural divisions of a musical note, we in the West have adopted in more recent times a musical system which is unnatural. We have chosen to divide the octave (from ‘ oct’ meaning eight) into twelve semi-tones. This is how the piano, the basis of all western overtone chant music, is designed. The ancient instruments mentioned above have one thing in common: they all, when played, produce the notes of the natural overtone scale. The piano, and most modern Western instruments produce a scale that, while mathematically understandable, does not conform precisely to the natural laws of Harmonics (overtones). This tuning is called “even temperament”. It has allowed us to create classical music for huge orchestras, and music of ever-growing complexity, while at the same time preventing us from resonating in harmony with the beautiful simplicity of creation and the natural overtone scale. This is one of the reasons why we feel musically “lost” and are always searching for something we cannot define.

Even though Western music has dedicated hundreds of years to developing melody, harmony, rhythm and other aspects of musical structure, the one thing it has neglected is the tone colour or overtones. A musical form that uses mainly the colours or timbre of the sound, sounds foreign to us, and requires a re-education of our ear and capacity for musical appreciation. The strange thing is that our brains are actually responding to overtones all the time, and are tuned in many ways to the ratios of the overtone scale, we have just forgotten on a conscious level what we know on a subliminal, subconscious level. Most people, when hearing overtones for the first time, experience a strange feeling of familiarity, as if they have heard these sounds before.

Therapeutic applications of Overtone Singing

Overtone singing has been discovered to have many therapeutic applications.

This effect, essentially a form of deep meditation, relieves stress, balances and clears the chakras (energy centres of the body), and creates a feeling of lightness and well-being. The sound of overtones helps to balance the two hemispheres of the brain, as it engages both the logical, reasoning left-brain, due to the mathematically precise proportions of the overtone scale, and the creative, intuitive right brain through the musical expression possible once one has become fairly proficient in the technique. This may be responsible in part for its attraction to a larger percentage of men than women. Women in general have a better balance between their brain hemispheres than men.

The harmonic ratios found on the overtone scale are, not surprisingly, found throughout Nature, and reflect the natural structure of all life on Earth. We human beings are no exception. Another famous Greek philosopher and mathematician, Plato, discovered that all things on this planet are made out of 5 basic building blocks. These shapes, called the Platonic Solids, can be found at the molecular level of all animate and inanimate objects. It is logical, if one believes in a Creator, that the same principles of creation would be applied to ALL of creation, and we are an integral part of it. When listening to or creating overtones, we begin to resonate in harmony with these primordial vibrations of which we are made, and which reflect our own atomic, molecular and cellular structure.


The incredibly high decibel levels to which we are exposed in the modern world, particularly in cities; The negative belief systems with which we are programmed by our teachers, governments, organised religions, commercial advertising, pharmaceutical companies and the medical and education system as a whole; Negative belief systems originating with our parents, family and friends; A high intake of toxic foods, chemicals and lack of proper nutrition.

These are just a few of the reasons why we might vibrate “out of tune” and thus experience ill health or sickness at the physical, mental, emotional or even spiritual levels.

Overtone singing, when practised with intention, can serve as a very powerful tool for vibrational “repatterning”, in other words, a way of re-programming our physical, mental and emotional bodies with a more harmonious, natural, “in tune” pattern. The beauty of this miraculous technique is that it bypasses the intellectual mind and goes right through to one’s essential being without being first analysed. (I use the term miraculous in the same way as in the book’ A Course in Miracles’ i.e. If you are not experiencing miracles daily in your life then something is wrong!). Analysis is an ancient human defence mechanism that helps us to make decisions based on experience, for the purpose of survival. But what happens when our experience, and the information with which we have been programmed is based on much incorrect information? How do we tell what is good for us or not?

Becoming aware of overtone singing, one begins a journey into the Voices of the Voice and the Sound within the Sound. When you hear or practise overtone singing you will know whether it is good for you or not. You will know on levels much more profound than analytical deduction. You will feel it resonate deep within you, where other primordial human qualities like intuition, instinct, unconditional love, compassion and joy reside.

You will vibrate in harmony with the Creation and feel one with it. You will come home, safe and Sound.
