128 Hz

128 Hz is two octaves below the 256 Hz “C” of scientific (Pythagorean) pitch. In Barbara Hero's mineral-correspondence table it is listed against the element sulfur; to bodyworkers it is simply the standard low-C tuning fork. Practitioners apply the 128 Hz fork for its slow, palpable vibration in relaxation and grounding work. Auriviel builds tracks on this C fundamental for a warm, settling low end — presented as music, not therapy. Independent of any tradition, controlled clinical evidence that a specific frequency produces a specific health effect is limited and mixed. Auriviel presents these tunings as music and contemplative practice. This page is for general information and relaxation. Auriviel's frequency music is not medical advice, diagnosis, or treatment, and no health outcome is claimed. If you have a medical concern, please consult a qualified professional.
