Solfeggio frequencies: the full list, from 174 Hz to 963 Hz

By Joanna · Published 11 November 2026

The Solfeggio frequencies are a set of nine tones, 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz, used in sound healing and played under meditation, affirmations and subliminals. The original six, 396 to 852 Hz, were popularised by Joseph Puleo and Leonard Horowitz in the 1990s, and the other three were added later.

Key takeaways

• The full list has nine tones: 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz.
• The original six (396, 417, 528, 639, 741 and 852 Hz) appeared in Puleo and Horowitz's 1999 book Healing Codes for the Biological Apocalypse . 174, 285 and 963 Hz came later.
• Each tone carries a name in sound-healing lists, such as "liberation" for 396 Hz and the "love frequency" for 528 Hz. These are traditional names, and Subliss makes no health claims for any sound.
• The Subliss builder offers seven of them as steady tones, from 396 Hz to 963 Hz, to play quietly under your own affirmations.

What are the Solfeggio frequencies?

The Solfeggio frequencies are specific pitches, measured in hertz (cycles per second), that sound-healing traditions treat as a set. Each one is a steady tone with no melody, and people play them as a background layer for meditation, yoga, affirmations and subliminals.

The name borrows from solfège, the do-re-mi syllables singers learn scales with, and the original six are often matched to the old syllables ut, re, mi, fa, sol and la. The tones are often described as ancient. Sound-healing writers who have traced them, including Sound Medicine Academy and NeuroBeatX , place their origin with Puleo and Horowitz, and note that early music had no standard pitch to set a tone at precisely 528 Hz.

The Solfeggio frequencies list

Here is the full set, in order, with the name each tone carries in sound-healing lists and whether you can add it in the Subliss builder.

The names come from sound-healing tradition, and some lists attach health claims to particular tones, such as pain relief for 174 Hz, tissue repair for 285 Hz and DNA repair for 528 Hz. Subliss leaves those claims out. The guide to 528 Hz covers the best-known tone in more detail.

Where do the Solfeggio frequencies come from?

The Solfeggio frequencies come from Joseph Puleo, who arrived at the six numbers by reducing figures to repeating digit patterns, and from Leonard Horowitz, who published them with Puleo in 1999. Horowitz later added 174, 285 and 963 Hz, which turned the six into the nine-tone list in wide use today.

People who enjoy the tones often point out a number pattern in them. Add up the digits of each original tone and reduce the total to one digit, and you always get 3, 6 or 9: for 396, 3 + 9 + 6 is 18, and 1 + 8 is 9. That pattern is why the tones come up alongside the 369 method , although the two are separate practices.

How do you use Solfeggio frequencies under affirmations?

Use one tone at a time, quietly, under your own voice. A single steady tone sits under spoken words without competing with them, as long as it stays low in the mix.

In the Subliss builder, the Frequencies group has seven steady tones, 396, 417, 528, 639, 741, 852 and 963 Hz. Free accounts get the first sound in each group, which here is 396 Hz, and Premium opens the rest. In the starting mix we use, a frequency sits at 1 to 4 percent, under a main sound such as rain at 30 to 50 percent. The step-by-step guide to making your own subliminal walks through the builder, mix and all.

Pick the tone you like the sound of, whether by its traditional name, 639 Hz for a list about friendship, say, or by ear.

Frequently asked questions

How many Solfeggio frequencies are there? Nine in the list most people use today: 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz. The original set had six.

Which Solfeggio frequency is the most popular? 528 Hz, often called the love frequency, is the one people search for most.

Do you need headphones for Solfeggio frequencies? No. A steady tone sounds the same in both ears, so speakers work too. Headphones matter for binaural beats, which rely on each ear hearing a slightly different tone.

Can you play more than one Solfeggio frequency at once? You can, but two steady tones together can clash. Under affirmations, one tone kept low is easier to listen to every day.

Choose a tone by how it sounds

The Solfeggio list is a set of nine numbers with names and stories attached. Under a subliminal, the right one is the tone you are happy to hear every day, kept quiet enough that your own words stay on top.
