528 Hz: what it is and how to use it under affirmations

By Joanna · Published 3 November 2026 · Last updated 11 November 2026

528 Hz is a single steady tone, a sound wave that repeats 528 times a second, and one of six "Solfeggio frequencies" that spread through sound healing after a 1999 book. People play it as a background tone for meditation, affirmations and subliminals, and that is the simplest way to use it: quietly, under your own words.

Key takeaways

• 528 Hz is a pure tone at 528 cycles a second. In standard tuning it sits between C (523.25 Hz) and C sharp (554.37 Hz), a little over an octave above middle C.
• It is one of six Solfeggio frequencies (396, 417, 528, 639, 741 and 852 Hz) popularised by Joseph Puleo and Leonard Horowitz in the 1990s.
• Sound-healing lists label it "transformation and miracles", and it is often called the "love frequency". Subliss makes no health claims for any sound, including the DNA-repair claim often attached to 528 Hz.
• Under affirmations, keep a frequency quiet. In the starting mix we use, it sits at 1 to 4 percent, well below the other sounds.

What is 528 Hz?

528 Hz is a tone that vibrates 528 times per second. Hertz, written Hz, is the unit for cycles per second, so 528 Hz describes a pitch in the same way that the A a musician tunes to is 440 Hz. Played on its own, it is a clear, steady hum with no rhythm or melody.

What note is 528 Hz?

528 Hz is a slightly sharp C, sitting between the C a little over an octave above middle C (523.25 Hz) and the C sharp above it (554.37 Hz) in standard tuning, where A is 440 Hz. It is about 16 cents above that C, roughly a sixth of a semitone.

Where does 528 Hz come from?

528 Hz comes from the Solfeggio frequencies, a set of six tones that Joseph Puleo and Leonard Horowitz popularised in the 1990s, including in their 1999 book Healing Codes for the Biological Apocalypse . The six are 396, 417, 528, 639, 741 and 852 Hz, and some lists add more, such as 963 Hz.

The name borrows from solfège, the do-re-mi syllables singers learn scales with, and the tones are often described as ancient. A guide by Sound Medicine Academy, a sound-healing school, notes that no historical record links the Solfeggio frequencies to early music and traces the idea to Puleo and Horowitz's work. The numbers are modern, and the practice built around them is about thirty years old.

What is 528 Hz good for?

People use 528 Hz as a steady background tone, under meditation, under affirmations and under subliminals. In sound-healing lists it carries the label "transformation and miracles", and it is often called the "love frequency".

You will also see 528 Hz sold with claims about repairing DNA. Subliss makes no health claims for any sound, so we leave those out. The builder treats 528 Hz as a tone you choose because you like how it sits under your voice.

How do you use 528 Hz under affirmations?

Use 528 Hz as a quiet layer under your own voice, lower than everything else in the mix. In the Subliss builder it is one of seven steady tones in the Frequencies group, from 396 Hz to 963 Hz, and you can add it under your affirmations alongside nature sounds, brainwaves, noise or melodies.

• Write a short list of affirmations in your own words. The guide to how to write affirmations covers the wording.
• Record the list yourself, or with Premium have an AI voice read it, then choose a speed. At 1x you hear every word. Speed it up and the words sit under the sound layers.
• Add 528 Hz from the Frequencies group, and a main sound such as rain if you want a fuller background.
• Mix the tone low. In the starting mix we use, a frequency sits at 1 to 4 percent, under a main sound at 30 to 50 percent.
• Save it. Subliss renders a looped track of about five minutes that you can play in the app.

How long should you listen to 528 Hz?

Under a subliminal, 528 Hz plays for as long as the track does, and there is no set length beyond that. In Subliss a track is a five-minute loop, so a daily goal of 10 minutes is two plays. For an affirmation practice, the habit worth building is coming back to the same track every day, and how to listen to subliminals sets out a daily routine. Keep the volume at a level you find comfortable.

Frequently asked questions

Do you need headphones for 528 Hz? No. A steady tone sounds the same in both ears, so speakers work as well as headphones. Binaural beats are different, because they rely on each ear hearing a slightly different tone.

Is 528 Hz free in Subliss? Free accounts get the first sound in each group, which in Frequencies is 396 Hz. 528 Hz and the other tones come with Premium.

What do the Solfeggio frequencies have to do with 369? Fans of the tones point out that the digits of each one add up to 3, 6 or 9. For 528, 5 + 2 + 8 is 15, and 1 + 5 is 6. The 369 method is a separate writing practice.

What are the other Solfeggio frequencies? The other five in the original set are 396, 417, 639, 741 and 852 Hz. The Subliss builder offers all six, plus 963 Hz. The full Solfeggio frequencies list covers all nine, with their names.

Choose 528 Hz for how it sounds

528 Hz has gathered a lot of stories in thirty years. Under a subliminal, its part is simpler: a steady, quiet tone that sits beneath your own words while you come back to them every day.
