417 Hz

417 Hz belongs to the modern Solfeggio set, whose values derive from a numerological reading of a medieval hymn rather than from acoustic measurement — a tradition rather than a tuning standard. Practitioners use 417 Hz in sound work oriented toward movement and renewal. Auriviel tunes tracks to this fundamental for that quality — offered as music for practice and listening, not as medical 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.
