528 Hz
Free healing-frequency, solfeggio & Om sound generator
The best-known solfeggio tone — press Play for an exact 528 Hz tone or a softer layered drone.
Start at a low volume and turn up slowly. Pure tones can sound louder than music at the same setting, especially higher frequencies.
| Frequency | 528 Hz (528 vibrations per second) |
|---|---|
| Nearest musical note (A=440) | C5 +16 cents |
| Wavelength in air | about 65 cm |
| Period of one cycle | 1.89 ms |
| Solfeggio syllable | Mi |
| Which set | Original six (Puleo) |
| Popular claim | Promoted as the "love frequency" and the "miracle tone", with claims of "DNA repair" (a claim, not a demonstrated effect) |
528 Hz is the "Mi" of the modern solfeggio scale. In the medieval hymn the syllable comes from "Mira gestorum" ("the wonders of your deeds"), and Leonard Horowitz, who popularised the frequencies in the late 1990s, built on that to call 528 Hz the "miracle" tone. Later promoters added the nickname "love frequency". Its digits reduce to 6 (5 + 2 + 8 = 15).
The most repeated claim about 528 Hz is that it "repairs DNA". There is no scientific basis for this. No controlled study has shown that listening to 528 Hz changes or repairs human DNA, and audible sound at a comfortable listening level does not reach or act on DNA in the way the claim implies. If you see this presented as fact, treat it as marketing.
A very small 2018 study from Japan (fewer than a dozen participants) compared music tuned to 528 Hz with the same music at standard 440 Hz tuning and reported lower stress-related measures after the 528 Hz version. It is interesting, but it is far too small to draw conclusions from, and it has not been confirmed by larger, independent trials. It also studied music tuned to 528 Hz, not a plain tone. The honest summary: 528 Hz may be a pleasant tone to relax with, like many others, and nothing more has been shown.
528 Hz is a slightly sharp C: C5 is 523.25 Hz in standard tuning, so 528 Hz is about 16 cents above. If you tune A to 444 Hz instead of 440 Hz, C5 lands on 528 Hz exactly — which is why some 528 Hz advocates promote an "A=444" tuning, much as others promote A=432.
Nobody has shown that a particular frequency heals the body, repairs DNA or treats a medical condition. The specific benefits attached to each solfeggio number are claims from the books and videos that popularised them, not findings from controlled research. What is well supported is more modest: calm, steady, predictable sound that you like can help you relax, mask distracting noise and give your attention somewhere to rest. Any of these tones can do that — and so can plenty of others.
Use it for: relaxation, meditation, a calm background while you read or rest, sound exploration, or simply because you like it. Don't use it as: a treatment for any medical or mental-health condition. For a deeper look at the whole set, see the solfeggio frequency list.
No. There is no scientific evidence that listening to 528 Hz repairs or changes DNA. That claim comes from solfeggio promoters, not from research.
It is the "Mi" tone, linked by solfeggio writers to the hymn phrase "Mira gestorum" (wonders, miracles). "Love frequency" is a later marketing nickname rather than a scientific term.
Only a little. A very small 2018 study reported lower stress-related measures with music tuned to 528 Hz versus 440 Hz, but it had fewer than a dozen participants and has not been replicated at scale.
It is about 16 cents above C5 in standard tuning. With A tuned to 444 Hz, C5 is exactly 528 Hz.
As long as it feels pleasant. Many people use 10 to 30 minutes for relaxation or meditation; use the sleep timer if you want it to stop by itself, and keep the volume low.
