There is no single best frequency for meditation established by the studies discussed here. You can try 528 Hz music, 432 Hz tuning, or another comfortable sound, but none of these studies identifies one frequency as best for everyone. Choose audio that lets you practise comfortably rather than relying on promises about healing or spiritual transformation.
The distinction matters because a playlist number can refer to a tone, a tuning reference, or a binaural beat. Those are different things, and research on one does not automatically support claims about another.
What are Solfeggio frequencies?
In wellness audio, Solfeggio frequencies usually means a named group of tones with emotional or spiritual associations. For example, the music platform HZP lists 396, 417, 528, 639, 741 and 852 Hz, with 174, 285 and 963 Hz as additions. HZP describes its associations as personal or traditional interpretations, not medical claims (HZP, What Are Solfeggio Frequencies?).
That commercial guide is useful for understanding the labels you encounter. It is not evidence that those labels describe measurable health effects.
You do not need to accept a frequency’s advertised meaning to enjoy a recording. Equally, enjoying it does not confirm the advertised explanation.
A tone, a tuning reference, and a beat are different
Hertz, abbreviated Hz, describes frequency. In a pure tone recording, the label refers to the tone itself. Music, however, contains changing notes and multiple sound components; an entire song is not one pure tone.
With 432 Hz music, the number commonly refers to a reference used to tune the music. Calamassi and Pomponi’s 2019 study in Explore compared versions of the same music tuned to 432 Hz and 440 Hz, rather than two isolated tones (study).
Binaural beats involve slightly different tones presented separately to the ears. The perceived beat relates to the difference between them, as explained by Ingendoh, Posny and Heine (2023), PLOS ONE (review). A binaural-beat label therefore cannot be interpreted in the same way as a pure-tone label.
Solfeggio frequencies meaning: the labels versus the evidence
The table summarizes associations used by HZP, a commercial music platform. These are descriptions of its frequency labels, not verified benefits (HZP frequency guide). The research cited below does not establish this chart as a treatment system.
| Frequency | Association used in wellness audio | What the cited evidence supports |
| 174 Hz | Ease and comfort | No specific pain treatment established here |
| 285 Hz | Restoration and renewal | No tissue-repair benefit established here |
| 396 Hz | Letting go of fear or guilt | No frequency-specific emotional treatment established here |
| 417 Hz | Change and clearing negativity | No trauma-clearing effect established here |
| 528 Hz | Transformation and clarity | Small exploratory study of music, not proof of DNA repair |
| 639 Hz | Relationships and connection | No relationship benefit established here |
| 741 Hz | Cleansing and self-expression | No detoxification effect established here |
| 852 Hz | Intuition and awareness | No intuition-enhancing effect established here |
| 963 Hz | Oneness and stillness | Spiritual association, not an established biological effect |
There is an important difference between using a label as an intention and treating it as a claim about your body. You might choose a track associated with connection while reflecting on a relationship. That does not mean the pitch repairs the relationship.
What research actually found about 528 Hz
The small study behind 528 Hz benefits
Akimoto, Hu, Yamaguchi and Kobayashi (2018), in Health, studied nine healthy adults listening to music described as 528 Hz or 440 Hz on separate days. Each listening period lasted five minutes. The authors reported changes in salivary cortisol and oxytocin, and improvements in some mood measures after the 528 Hz condition (study).
Those findings are exploratory. The sample was small, the exposure was brief, and the study examined music listening rather than comparing meditation practices.
There is also a statistical caution: a significant before-and-after change in one condition, but not another, does not by itself establish a significant difference between the conditions. The paper’s reported analysis emphasizes comparisons over time within each condition (Akimoto et al., 2018, Health).
The study does not identify 528 Hz as the best frequency for meditation. It also did not test DNA repair, disease recovery, or lasting emotional healing. Those claims go beyond its measurements.
Is a 528 Hz pure tone the same as the studied music?
No. Akimoto and colleagues describe soothing piano music in their methods, not a standalone 528 Hz sine tone (2018, Health).
You cannot assume that an online pure-tone track reproduces the intervention. A recording’s title does not tell you whether it matches the study’s music, sound level, equipment, or listening conditions.
If you enjoy a 528 Hz track, you can use it. Describe the experience simply: the recording felt pleasant or helped you stay with the exercise. You do not need to claim that it changed your DNA.
Is 432 Hz better than 440 Hz for meditation?
Calamassi and Pomponi (2019), in Explore, conducted a crossover pilot study with 33 healthy volunteers listening to the same music under different tuning conditions. They reported a greater reduction in heart rate with 432 Hz tuning and called for further research (study).
A later trial by Hohneck and colleagues (2025), in BMC Complementary Medicine and Therapies, compared sound interventions tuned to 432 Hz and 443 Hz in 43 patients with cancer. Both conditions showed improvements in several self-reported outcomes, while some cardiovascular findings differed (study).
Neither study establishes that 432 Hz produces better meditation. A short-term physiological result is not a measure of meditation skill, and a clinical sound intervention does not automatically generalize to a home playlist.
What about a 432 Hz tuning fork?
A tuning fork is a different intervention from listening to recorded music or receiving a body-monochord sound session. The studies above do not establish a benefit from placing a 432 Hz fork on the body.
Choose a fork if you enjoy its sound, not because these papers prove that a consumer tuning fork treats anxiety or illness. There is no need to buy special equipment to try meditation with sound.
What about 174, 417, 639, 741, 852 and 963 Hz benefits?
174 Hz and 417 Hz: comfort and change
Comfort and change can be intentions for a practice. They should not become promises of pain relief or removal of past trauma simply because a track carries those labels.
If you use a 417 Hz track while reflecting on change, focus on what you want to do differently. You can write down a concern, identify an available next step, or decide that you need support. The sound does not make those decisions for you.
639 Hz and 741 Hz: connection and self-expression
You could pair a connection-themed track with thoughts about listening more carefully or having a difficult conversation. You could use a self-expression theme as a journaling prompt.
These are choices about how to structure reflection. The studies in this article do not show that 639 Hz improves relationships or that 741 Hz removes toxins.
Avoid turning a symbolic word such as cleansing into a medical claim. A meaningful ritual and a tested health intervention require different kinds of evidence.
852 Hz and 963 Hz: intuition and spiritual beliefs
Intuition, awareness and oneness are spiritual or personal interpretations in this context. The cited research does not establish that these tones activate a gland or create a particular spiritual state.
You can respect an interpretation while remaining clear about what it means to you. LifeNByte takes a similar approach when discussing spiritual beliefs about déjà vu alongside practical explanations.
Are binaural beats better for meditation?
Binaural beats have a separate research literature. They should not be used as evidence for the Solfeggio chart.
Garcia-Argibay, Santed and Reales (2019), in Psychological Research, reported an overall beneficial effect across studies examining cognition, anxiety and pain perception. Their meta-analysis did not identify one universal meditation frequency (review).
Ingendoh, Posny and Heine (2023), in PLOS ONE, reviewed studies examining whether binaural stimulation entrains brain activity. They found inconsistent results and substantial differences in methods (review).
These reviews address different questions. A possible effect on an outcome does not automatically prove that a recording puts the brain into a chosen state.
Do you need headphones?
For a conventional binaural-beat recording, headphones provide the separate signals to each ear required by the method described by Ingendoh and colleagues (2023), PLOS ONE (review).
Ordinary music does not require that arrangement. If headphones are uncomfortable, choose a speaker or practise without audio. You do not need binaural beats to follow the exercise below.
What is the best frequency for sleep?
No specific pitch is established as the best sleep frequency by the evidence discussed here.
Jespersen and colleagues (2022), in the Cochrane Database of Systematic Reviews, found moderate-certainty evidence that music improved self-reported sleep quality in adults with insomnia symptoms. Evidence for other outcomes was less certain, and objective sleep measures did not show clear improvements (Cochrane review).
That supports discussing music as a possible sleep aid. It does not establish 528 Hz, 963 Hz, or another Solfeggio pitch as the active ingredient.
Choose a recording you find comfortable, without sudden changes that you dislike. A timer is an option if you prefer the sound to stop after your bedtime routine.

How to choose sound for meditation without chasing a number
Start with the practice you want to do. If you want to attend to breathing, the audio should be easy to leave in the background. If you want to use sound as the focus, you can attend to the recording itself.
A simple listening practice
- Choose one recording or silence. Begin with something you already find comfortable. A frequency label is optional.
- Set the sound low. Start in a quiet place and avoid increasing the volume to cover every outside noise.
- Sit comfortably. Use a chair or cushion. Leave your eyes open or closed as you prefer.
- Choose an anchor. Attend to breathing, a bodily sensation, or the sound. When you notice your attention has moved, gently return.
- Review the experience. Ask whether the audio was comfortable and whether you want to use it again. You do not need to interpret it as healing.
This is a suggested practice, not a research-tested frequency protocol. Keep it brief at first and adjust to your comfort. If you are new to sitting practice, our beginner’s guide to meditation covers the basics.
Compare recordings fairly
Compare a familiar track with another recording, or with silence, over separate sessions. Keep your setup similar if you want a useful personal comparison.
Notice practical details: Was the sound irritating? Did you keep adjusting it? Would you willingly use it again?
This cannot isolate the effect of pitch. The recordings may also differ in melody, rhythm, volume and what you expect from them. A preference is still useful; it just is not a scientific result.
Keep listening comfortable
The World Health Organization’s safe-listening guidance recommends limiting volume and listening duration, and using sound-exposure monitoring where available (WHO, Safe Listening). A meditation label does not change those precautions.
Stop if the sound is uncomfortable. If you have persistent hearing symptoms or ongoing sleep or anxiety difficulties, seek appropriate care rather than relying on a frequency playlist.
Frequently asked questions
The cited studies do not identify one frequency as best for everyone. Start with a comfortable recording or silence, and choose according to your practice rather than a healing claim.
Akimoto and colleagues’ 2018 study in Health examined short-term responses to music, not DNA repair (study). It cannot support that claim.
The studies discussed here do not provide a reliable head-to-head ranking for meditation. Pick the recording you prefer without treating the number as a guarantee.
Change and clearing negativity are associations used in wellness audio, not established outcomes from the research cited here. You can use the theme as a reflection prompt without expecting it to erase experiences or emotions.
None of the research discussed here establishes a detoxification effect from 741 Hz audio. A recording described as cleansing should not be treated as a medical treatment.
Oneness and stillness are spiritual or personal associations. The cited sources do not establish that listening to 963 Hz activates the pineal gland or produces a guaranteed state of awareness.
Ordinary tone or music recordings can be played through a speaker. Conventional binaural beats require separate signals to each ear, typically through headphones, as described by Ingendoh and colleagues (2023), PLOS ONE (review).
There is no need to play it all night to follow the practices in this article. Consider a timer, keep the volume low, and follow WHO guidance on volume and listening duration (World Health Organization).
Bottom line
Choose meditation audio for comfort and usefulness, not promises attached to a number. Some music and binaural-beat studies report encouraging results, but they do not validate the full Solfeggio healing chart or identify a universal best frequency. Silence remains an available choice.
