555.1 Hz

555.1 Hz is a tone Barbara Hero connected to Hindu cosmological number-lore, the vast cycles of yugas and kalpas by which that tradition measures cosmic time. Rendered through the Lambdoma's whole-number ratios, the proportion becomes an audible pitch. Like the rest of Hero's planetary family, it translates a number of time and place into sound: a contemplative, numeric correspondence offered for listening. This small family gathers pitches connected to the geometry of the Earth's surface (the so-called planetary grid) and to number-lore such as the Hindu cosmological cycles. They extend Hero's Lambdoma approach outward from the body to the planet, translating proportions of place and time into sound. 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.
