396 Hz

396 Hz is the first frequency of the modern Solfeggio set popularised in the late twentieth century. The Solfeggio numbers come from a numerological reading of a medieval hymn rather than from acoustic measurement, so they are best understood as a tradition, not a scientific tuning standard. In sound-healing practice 396 Hz is used for grounding and release work. Auriviel offers a Lambdoma tone built on this fundamental for meditation and focus — a contemplative tool, not a treatment for any condition. 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.
