Who we are

Nestor and Michêle, directors of the association, conduct intensive courses on the therapeutic and transformational uses of sound, and particularly the voice. Through vocal harmonics (overtone chant) and many other vocal techniques, a course participant is taken on a ‘Sound Journey’ through the physical, emotional, mental and spiritual dimensions of sound.

Employing knowledge which ranges from ancient shamanic practices to modern scientific techniques, they ensure that everybody receives and takes home useful and powerful tools for personal (and planetary) transformation. ‘Planetary’ because sound spreads out in all directions from the source. When a group of people tone or sing together with a common intention, they create a waveform that can literally influence consciousness on a global scale.

Nestor and Michêle are married and live in Alcalalí, Costa Blanca with their three children.
