Solfeggio Frequencies

The Solfeggio frequencies are a set of specific tones used in sound healing practice, most famously 528 Hz (sometimes called the "love frequency" or "DNA repair frequency") and 432 Hz (sometimes called "natural tuning" as opposed to standard 440 Hz concert pitch).

The Solfeggio frequencies trace to a 1970s reinterpretation of medieval Gregorian chant scales, and were popularized in modern sound healing literature beginning in the 1990s. There is no clinical evidence that these specific frequencies have measurable effects beyond the general psychoacoustic effects of sustained tones.

We list Solfeggio-tuned tuning forks and singing bowls as 5 on the Woo-Woo Meter — beautifully made instruments for a real practice, not medical devices.
