528 Hz and solfeggio frequencies: what the evidence says
Claims that 528 Hz or other solfeggio frequencies heal DNA, cells or emotions have no scientific support. The only study usually cited tested music tuned to 528 Hz in nine people for five minutes. It found small stress-related changes, but it is far too small to support any health claim, and its authors note that solfeggio claims lack a scientific basis.
Is 528 Hz a healing frequency? The only study is of 9 people, and its own authors say solfeggio claims lack a scientific basis. What we know.

Evidence: Insufficient for any health or healing effect
See what the evidence says about music and stressHow to do it
- If you enjoy music tuned this way, enjoy it as music. Its calming effect is likely the music itself.
- Be wary of products that charge more for a 'healing frequency'.
What the research shows
Akimoto and colleagues played nine adults five minutes of piano music tuned to 528 Hz on one day and standard 440 Hz tuning on another. After the 528 Hz version, cortisol fell and some mood scores improved.
With nine participants, one short exposure and no correction for multiple comparisons, the study cannot show that 528 Hz has special effects. The authors themselves state that the purported benefits of solfeggio frequencies have no scientific basis.
What "Insufficient" means here: Little or no credible research for the claims usually made. Rated for: Any health or healing effect.
Key studies
- Effect of 528 Hz Music on the Endocrine System and Autonomic Nervous System
Akimoto K, Hu A, Yamaguchi T, Kobayashi H. Health, 2018 · Within-person comparison, 9 adults, one 5-minute exposure
Small changes in cortisol and mood after 528 Hz music; far too small to support health claims.
Safety notes
- No frequency replaces medical care.
Common questions
Does 528 Hz repair DNA?
No. There is no credible research showing any sound frequency repairs DNA.
