Jill Purce is a British voice teacher, Family Constellations therapist, and author. In the 1970s Purce developed a new way of working with the voice, introducing the teaching of group overtone chanting, producing a single note whilst amplifying the vocal harmonics.

Jill pioneered the international sound healing movement through her rediscovery of ancient vocal techniques, the teaching of overtone chanting, the power of group chant, and the spiritual potential of the voice as a magical instrument for healing and meditation. She pioneered the practice of healing family and ancestral traumas with her Healing Family and Ancestor and Resonant Family Constellations, and the activation of the mandala as a living practice with her extended Mandala Ceremonies.
