Frequencies.
432, 528, 963 Hz and solfeggio.
The frequencies people search for most: 432 Hz, 528 Hz, 963 Hz and the full solfeggio list. Each article sets out what is claimed, then says plainly what the evidence does and does not show.
528 Hz frequency: benefits, claims, and what the evidence says 528 Hz frequency benefits are mostly claims. One study of 9 people found lower stress hormones after 5 minutes of 528 Hz music; nothing shows it repairs DNA. 432 Hz frequency: benefits, 432 vs 440 Hz, and what the evidence says The main 432 Hz frequency benefit with any evidence is a small drop in heart rate: about 4.8 beats per minute in one pilot study of 33 people. 963 Hz frequency benefits: what is claimed and what the evidence says 963 Hz frequency benefits come from sound healing tradition. No study has tested 963 Hz itself; the closest studies used 528 Hz (9 people) and 432 Hz (33). Solfeggio frequencies list: what each one is and what the evidence says The nine solfeggio frequencies run from 174 Hz to 963 Hz. Each has a traditional meaning, but the only human study we found tested 528 Hz on 9 people.
