What people say about 417 Hz
417 Hz is one of the nine Solfeggio frequencies, linked with the old singing syllable "Re". Said to clear away the past and make way for change.
What we know
No good research shows that 417 Hz, or any single frequency, heals or changes the body on its own. The Solfeggio tones are a modern idea from the late twentieth century, not an ancient one. What is real is quieter: a steady, pleasant sound gives a wandering mind somewhere to rest. Take the popular meaning as an intention for your sitting, not a promise. More about the Solfeggio tones.
