194.18 Hz

Cousto derived 194.18 Hz by octave-doubling the period of one solar day — the Earth's rotation — into the audible range, near a G. In his chakra mapping this tone anchors the root centre. The Earth-day tone is used in grounding and meditation practice for its steady, centring quality. Auriviel tunes audio to this fundamental for a grounded foundation — offered as music for focus and rest, not treatment. 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.
