Solfeggio Frequencies

The Solfeggio frequencies — a set of tones (396, 417, 528, 639, 741, 852 Hz, with 285 and 963 sometimes added) popularised from a numerological reading of a medieval hymn. They are a tradition, not a tuning standard, and Auriviel treats them as exactly that.

Below are the Solfeggio tones we have built real, tuned audio for, each with a sourced hub explaining its origin and how the tradition uses it. Listen to the music, read what is attributed, and decide for yourself — it is offered as contemplative practice, never as medical treatment.
