Quick answer528 Hz is one of the so-called solfeggio frequencies, often called the "love frequency". 528 Hz music is built around a tone that vibrates 528 times per second, close to the musical note C. One small study (9 people) found lower stress hormones after 528 Hz music, but claims that it repairs DNA have no scientific support. As sleep music it helps the way calm music does: it slows you down so you can rest.
Listen: 528 Hz deep healing music for sleep (8 hours)
Press play for eight hours of 528 Hz music: slow, steady tones built around the 528 Hz frequency, with no sudden changes, so you can leave it on all night. It is inspired by the Emerald Tablet, the old Hermetic text behind the saying "as above, so below".

What is the 528 Hz frequency?
A frequency is measured in hertz (Hz): the number of times a sound wave vibrates each second. A 528 Hz frequency vibrates 528 times per second. In standard tuning (A = 440 Hz) the nearest note is the C above middle C, which sits at 523.25 Hz, so 528 Hz is that C raised by a tiny 15.6 cents. If an instrument is tuned to A = 444 Hz, its C lands exactly on 528 Hz, which is why some musicians use that tuning for 528 hz music.
People also search for it as 528hz, 528 hertz or the 528 Hz love frequency. Fans call it the frequency of love, transformation and "miracles". Those names come from the solfeggio story below, not from science.
528 Hz and the solfeggio frequencies
528 Hz belongs to a set of nine tones known as the solfeggio frequencies. They were popularised in the 1970s by Joseph Puleo, who said he found them through numerology in Bible verses, and later by Leonard Horowitz in the 1999 book Healing Codes for the Biological Apocalypse. Promoters link them to the medieval hymn Ut queant laxis, which gave us the note names ut, re, mi, fa, sol, la; 528 Hz is said to be "mi". Music historians point out that medieval singers had no fixed frequencies at all, so the numbers are modern, not ancient.
| Frequency | What promoters claim |
|---|---|
| 174 Hz | Pain relief, grounding |
| 285 Hz | Healing tissue |
| 396 Hz | Releasing fear and guilt |
| 417 Hz | Undoing situations, change |
| 528 Hz | Transformation, "love", DNA repair |
| 639 Hz | Relationships, connection |
| 741 Hz | Expression, "detox" |
| 852 Hz | Intuition |
| 963 Hz | Spiritual connection |
These are claims, not proven effects. Many people still enjoy solfeggio and 528 Hz music because it is slow and soothing, and that is a perfectly good reason to listen.
Hear a pure 528 Hz tone
528 Hz tone player
Play a pure 528 Hz tone, then compare it with the standard C (523.25 Hz) and with 432 Hz. Pressing another button changes the tone smoothly.
Press a button to hear the tone. Start with your volume low.
These are pure sine tones, not music. Start with the volume low; a pure tone can feel sharp after a while, which is why our sleep music softens it with warm pads. The tones are made in your browser.
Does 528 Hz healing work? What the studies say about sound healing
| Study | Who | What they found |
|---|---|---|
| Akimoto et al., 2018 | 9 healthy adults, piano music at 528 Hz and 440 Hz on different days | After 528 Hz music: lower cortisol (a stress hormone), higher oxytocin and less tension and anxiety on a mood test. After 440 Hz music, most of these changes were not significant. Tiny study with no silent comparison. |
| Goldsby et al., 2017 | 62 adults at a singing bowl sound meditation | Less tension, anger, fatigue and low mood afterwards. Shows that sound healing sessions can feel relaxing; it did not test 528 Hz and had no control group. |
| Cochrane review, 2022 | 13 trials, just over 1,000 adults with insomnia | Calm music at bedtime improved sleep quality (moderate-certainty evidence). The trials used slow relaxing music, not a special frequency. |
Our honest reading: there is good evidence that calm music and sound healing sessions help people relax and sleep, and one very small hint that 528 Hz might add to it. There is no evidence that 528 Hz repairs DNA, cures disease or changes your body at a cellular level. Enjoy 528 Hz deep healing music for what it does well: helping you slow down.
Healing frequencies for the body: claims vs evidence
| Claim about 528 Hz | What the evidence says |
|---|---|
| "Repairs DNA" | No human evidence. This claim comes from the solfeggio books, not from research. |
| "Reduces stress" | One study of 9 people found lower cortisol. Promising but far from proven. |
| "Helps you sleep" | Calm, slow music does help sleep quality; 528 Hz music can work as calm music. |
| "Opens the heart, the love frequency" | A spiritual idea, not something science can measure. Many listeners find it uplifting. |
| "Raises your vibration" | Not a scientific concept. Feeling calmer is real and worth having. |
If you are looking for frequency healing for a health problem, use music as a comfort alongside proper care, never instead of it.
How to listen to 528 Hz music for deep sleep
- Press play when you lie down and let the first minutes be your signal to rest.
- Keep the volume low. 528 Hz sits in the middle of the hearing range and can feel bright if it is loud.
- Use a speaker or sleep headphones, not hard earbuds.
- Breathe out slowly for a few minutes. Longer out-breaths calm the nervous system, and the steady tones give you something gentle to follow.
- Let the day go. The Emerald Tablet theme is about release: picture setting down whatever you carried today.
528 Hz or 432 Hz for sleep?
528 Hz is a single tone from the solfeggio set, so 528 Hz music circles around one bright, clear note. 432 Hz is a tuning for whole pieces of music, which sounds softer and lower. If you like a clear, "uplifting" sound, try 528 Hz; if you prefer something deeper and darker for sleep, try our 8-hour 432 Hz music. Neither has strong scientific proof of healing, so pick the one that relaxes you more.
Frequently asked questions
What does 528 Hz do?
528 Hz music works mainly as calm, steady sound that helps you relax. In one small study of 9 adults, it was linked with lower stress hormones and less anxiety. It has not been shown to heal illness.
Does 528 Hz repair DNA?
No. There is no scientific evidence that 528 Hz or any sound repairs human DNA. The claim comes from books about the solfeggio frequencies, not from research.
Why is 528 Hz called the love frequency?
The nickname comes from the solfeggio frequencies story, where 528 Hz is linked to love, transformation and "miracles". It is a spiritual label, not a scientific one.
Can I listen to 528 Hz music all night?
Yes, at a low volume. Our 528 Hz music lasts 8 hours and has no sudden changes. Use a speaker or sleep headphones and set a timer if you wake up easily.
528 Hz vs 432 Hz: which is better for sleep?
There is no proof that one is better. 528 Hz is a single bright tone; 432 Hz is a softer tuning for whole pieces of music. Try both and keep the one you find more calming.
What is sound healing?
Sound healing uses sounds such as singing bowls, gongs, tuning forks or steady tones to help people relax. Studies show it can reduce tension and improve mood, but it is a relaxation practice, not a medical treatment.
What are the healing frequencies for the body?
The best known are the nine solfeggio frequencies (174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz) and 432 Hz tuning. Their specific health claims are not proven; their real benefit is relaxation.
