The Complete Solfeggio Frequencies List (and What Each One Does)
The solfeggio frequencies are a set of ancient tones each linked to a different intention — from grounding to intuition. This guide gives the complete list, what each frequency is traditionally used for, and how to listen.

- The core solfeggio set has six original tones — 396, 417, 528, 639, 741 and 852 Hz — often extended to nine with 174, 285 and 963 Hz.
- Each frequency is traditionally associated with a specific intention, from grounding (396 Hz) to spiritual connection (963 Hz).
- 528 Hz sits at the centre and is the most popular, nicknamed the "Love Frequency".
- The frequencies trace back to sacred chant and were reintroduced to modern audiences in the 20th century.
- Formal scientific evidence is limited; the strongest, most consistent effect is deep relaxation.
The solfeggio frequencies are a family of tones, each traditionally tied to a different intention — releasing fear, opening intuition, deepening connection. This is the complete list, what each one is used for, and an honest note on the evidence. Bookmark it as your reference.

Where the solfeggio scale comes from
“Think of the solfeggio scale less as medicine and more as a set of doorways — each tone an invitation to a different state of mind.”
The tones are linked to an ancient six-note musical scale used in sacred chant, later reintroduced to modern listeners in the twentieth century. Whatever their exact history, they have become the backbone of contemporary sound healing — you will hear them across meditation, sleep and relaxation music, including our Cortisol Detox and Nervous System Regulation playlists.
How to use them
Pick the intention that fits your moment — 396 Hz to let go of anxiety, 528 Hz to feel restored, 963 Hz for meditation — and listen at a low, comfortable volume for 10–30 minutes. For sleep, our guide to solfeggio frequencies for sleep covers the best tones and routine. Treat the frequencies as a calming ritual rather than a medical treatment; the reliable benefit is relaxation.
Frequently asked questions
How many solfeggio frequencies are there?
There are six original solfeggio frequencies (396, 417, 528, 639, 741, 852 Hz), commonly extended to nine by adding 174, 285 and 963 Hz.
What is the most powerful solfeggio frequency?
There is no single "most powerful" tone — it depends on your intention. 528 Hz is the most popular and widely studied, while 963 Hz is favoured for meditation and 396 Hz for releasing fear.
Are solfeggio frequencies scientifically proven?
Evidence is limited and early. Some small studies suggest relaxation benefits, but the consistent, well-supported effect is that calm, low music aids relaxation. Treat the specific claims as traditional rather than proven.
Which solfeggio frequency is best for sleep?
Lower, calming tones like 174 Hz and 528 Hz are popular for sleep because they feel warm and grounding. What matters most is that the music is slow, soft and continuous.
