Nestor Kornblum

Nestor Kornblum (South Africa/Spain) 

Director and co-founder of both The Association of Sound Therapy and Harmonic Studies (Spain) and the International Association of Sound Therapy, Nestor is an internationally acclaimed Sound Therapist and overtone singer. He is author of the acclaimed guidebook on overtone singing with CD “Overtone Chant-the Practical Guide”

Since 1995, Nestor has explored and practiced the ancient art of overtone singing, also referred to as vocal harmonics, with particular attention to its therapeutic and meditational uses. An experienced teacher, he has now taught thousands of people the techniques of overtone singing and Sound Healing on 5 continents. He is among few in the western world to master the “Deep Voice” overtone chanting employed by Tibetan monks and Tuvan and Mongolian singers, which enables him to sing up to four simultaneous notes, with a range of 5 octaves.

Together with his wife and partner in Sound, Michele Averard, Nestor has facilitated one of the longest-running Sound Therapy Diploma Training courses in Europe, designed to empower participants to practice as Sound Therapists and incorporate sound healing into their other therapeutic modalities. Michele and Nestor together developed this well-balanced and all-round training in voice and other sound healing tools and instruments.

Nestor facilitates regular courses on sound healing, overtone singing and sound as a tool for personal and planetary transformation in English and Spanish,. Many of his courses are held in The Dome Center in Spain. The Dome is a large hemispheric structure especially designed by Nestor and Michele, for its spectacular acoustics that amplify the subtle tones of the voice and acoustic instruments.

He has been interviewed many times on television, radio and in the press in the countries where he presently works, as an expert on Sound Therapy. He has also written articles in English and Spanish on Sound Therapy which have been published in many of the countries he regularly visits. Nestor has frequently been invited to participate in Sound Healing Conferences, both live and online.

Nestor is an eloquent and charismatic speaker and teacher, able to express complex concepts in easily understood terms, with plenty of humour, and is no stranger to large audiences. He is thoroughly versed in the science and practice of Sound as a healing modality.


Nestor plays a variety of instruments including didgeridoo, monochord, tanpura, jaw’s harp, overtone flute, Native American flute, musical mouth-bow and assorted percussion.
