528 Hz is the most famous Solfeggio frequency — the central tone of the scale, popularly called the “Love frequency” or “Miracle tone.” You will often see it linked to “DNA repair.” That phrase is a cultural association from sound-healing literature, not a proven medical effect. We do not claim 528 Hz repairs DNA; below we explain honestly where the idea comes from and what research actually exists.
Where the 528 Hz association comes from
528 Hz sits at the heart of the reconstructed Solfeggio scale (the syllable Mi, from “MI-ra gestorum” — “miracle”). Author Dr Leonard Horowitz popularised the “DNA repair” association in the 1990s, and it spread widely online. It has become the emblem of the whole Solfeggio idea — which is exactly why it deserves careful, honest framing.
How people listen to 528 Hz
Some small studies are genuinely interesting: a 2018 study found that five minutes of 528 Hz music lowered salivary cortisol and raised oxytocin compared with 440 Hz, and laboratory (cell-culture) work has reported protective effects — but a cell study cannot tell us what a person will feel. Many listeners simply find 528 Hz warm and uplifting. Explore the research on our studies page, and treat it as a tone to experience, not a treatment.

Does 528 Hz really repair DNA?
No — there is no credible evidence that listening to 528 Hz repairs human DNA. The phrase comes from sound-healing literature, and a couple of laboratory studies on cells in a dish are sometimes cited, but those do not show any DNA-repair effect from listening to music. Enjoy 528 Hz as a tone, not as a therapy.
Is 528 Hz dangerous?
No. At a comfortable volume, a 528 Hz tone is no more dangerous than any other quiet music. As always, keep the volume moderate and take breaks to protect your hearing.
Why is 528 Hz called the love frequency?
It sits at the centre of the Solfeggio scale on the syllable 'Mi' (from a Latin word for 'miracle'), and sound-healing tradition tied it to the heart and to themes of love and transformation. The name is cultural, not scientific.
What note is 528 Hz?
528 Hz is close to C5 (523.25 Hz in standard tuning), about 16 cents sharp.
What is the difference between 528 Hz and 432 Hz?
528 Hz is a single Solfeggio tone associated with the heart and transformation; 432 Hz is an alternative way to tune whole pieces of music. They are different ideas — one is a tone, the other is a tuning standard.
A note on claims. The associations described here reflect sound-healing tradition and how people perceive these tones — they are not medical facts. Solfeggio frequencies are not a treatment for any condition. If you have a health concern, please speak with a qualified professional.
