You've probably seen the charts on TikTok and Instagram: a glowing body wrapped in golden rings, each labelled with a frequency and a benefit. These are the solfeggio frequencies — a set of tones people use for meditation, relaxation, and sound healing. Here's what each one is said to do, where they came from, and an honest look at whether they work.
What are solfeggio frequencies?
Solfeggio frequencies are a set of nine specific sound frequencies, from 174 Hz up to 963 Hz, used in sound therapy and meditation. Each tone is traditionally linked to a particular benefit or energy centre (chakra). People listen to them as pure tones, background music, or guided meditation tracks.
The 9 solfeggio frequencies (chart)
- 174 Hz — said to ease pain and give a sense of safety and grounding.
- 285 Hz — said to support tissue and energy-field repair.
- 396 Hz — said to release fear and guilt (root chakra).
- 417 Hz — said to clear negativity and support change (sacral chakra).
- 528 Hz — the “love frequency,” said to aid transformation, calm, and repair (solar plexus).
- 639 Hz — said to support relationships and connection (heart chakra).
- 741 Hz — said to cleanse, detox, and aid self-expression (throat chakra).
- 852 Hz — said to awaken intuition and inner order (third eye).
- 963 Hz — the “crown” tone, said to connect to higher consciousness.
Where did they come from?
The modern solfeggio set was popularised in the 1970s by Dr. Joseph Puleo, who said he uncovered the numbers by applying a numerology method (Pythagorean reduction) to verses in the Book of Numbers in the Bible. The six “core” tones — 396, 417, 528, 639, 741, and 852 Hz — come from that work, with 174, 285, and 963 Hz added later.
Do solfeggio frequencies actually work?
Here's the honest part. There is little scientific evidence that any specific frequency has special healing powers, and historians note there's no real record of ancient cultures using these exact tones. Claims like “528 Hz repairs your DNA” are not proven, and health claims like that deserve healthy skepticism.
What is well supported is that calm, pleasant sound — of almost any frequency — genuinely helps people relax, focus, sleep, and lower stress. So the honest takeaway: enjoy solfeggio frequencies as a soothing meditation and relaxation tool, not as a medical treatment.
How to use solfeggio frequencies
- Pick a tone that matches your intention — calm, focus, or sleep.
- Use headphones at a comfortable volume in a quiet space.
- Listen for 10–30 minutes while relaxing, meditating, or drifting off.
- Notice how you feel — a calmer, more present state is the real goal.

Puleo derived the numbers in the 1970s from a numerological reading of the Book of Numbers.

ISO 16:1975 — Acoustics: Standard tuning frequency (Standard musical pitch).Standard concert pitch of A=440 Hz was not fixed until the 20th century, which is why claims that medieval chant was tuned to specific solfeggio frequencies do not hold: there was no standardised pitch to tune to.
