Overtone Singing

Overtone singing is the art of singing two notes simultaneously with a single voice. To be more precise: overtone singing is a vocal technique that filters out individual overtones from the voice’s sound spectrum in such a way that they are perceived as separate notes, creating the auditory impression of polyphony. It is a fascinating, archaic sound experience. It sounds as though, in addition to the sung note, a sort of magical flute is being played at the same time.

More and more people are taking an interest in overtone singing for a wide variety of reasons.

The good news is that overtone singing can be learnt.

As overtones are a natural part of the sound of the voice, it can be said that anyone who can speak can also learn overtone singing.

Learning and practising overtone singing is far more than simply mastering a new singing technique. Exploring overtones sharpens the ear and opens up the resonant chambers, which in turn leads to a clear and melodious speaking and singing voice.

Consciously perceiving and training the overtones in one’s own voice can have a deeply harmonising and calming effect, as the English term for overtones – ‘harmonics’ – suggests.

‘At a time when the prevailing trend in the field of acoustic art is to either alter everything electronically or even generate it entirely electronically, it is a truly exciting endeavour to return to the sources, to re-appreciate the voice as a musical instrument, and to elevate it to the standard by which music, in the broadest sense, can be measured.’ Michael Vetter

Singers, singing enthusiasts and musicians

Overtone singing promotes precise control over formants and trains and activates the ability to hear overtones. Intonation is improved using the pure intervals of the overtone series. Overtone singing techniques offer exciting new creative possibilities in the fields of new music and improvisation.

Learning this vocal technique takes relatively little time and is great fun (it’s addictive). It’s well worth investing a few hours in this niche area of vocal pedagogy.

Therapists and those with an interest in spirituality

Consciously listening to and controlling overtones requires focus – this enhances mindfulness and the ability to concentrate. Overtone singing has a meditative and calming effect. For many, the sounds produced during practice are very harmonious and relaxing, much like breathing exercises or meditation. The parasympathetic nervous system is activated (‘rest-and-digest’ mode), which contributes to relaxation, a lower heart rate and improved recovery. Perceiving the vibrations in the body’s resonant chambers can help one to become more aware of and process emotions – much like in sound therapy or music therapy.

Speakers and presenters

Those who practise overtone singing learn to control their voice much more consciously. Breathing, resonance chambers and articulation are used in a targeted manner, which also benefits speech. The voice becomes more flexible, powerful and nuanced.
