Important things to understand before you listen.

Not medical advice

Nothing on this site is medical, psychological, psychiatric, therapeutic, or health advice of any kind. We do not diagnose, treat, cure, or prevent any disease, condition, or symptom. The content on this site is for general informational and educational purposes only.

If you have a medical or mental health concern — including pain, sleep issues, anxiety, grief, trauma, chronic conditions, or anything else — consult a qualified healthcare professional. Do not rely on any music, frequency, app, or article on this site in place of professional care.

No therapeutic or health claims

Frequencies do not cure, heal, repair DNA, remove trauma, reverse aging, attract wealth, guarantee spiritual awakening, or produce any specific medical, psychological, or metaphysical outcome. Any such claims — whether on this site, in linked apps, in sound-healing books, or elsewhere online — are not supported by established scientific evidence. We do not endorse them.

When we describe a frequency as "commonly associated with" love, grounding, release, intuition, or any other theme, we are reporting what modern sound-healing frameworks say about that frequency. We are not claiming the frequency causes that effect.

Retuning is a personal listening choice

Retuning music is a listening practice. Some people enjoy it. Some people do not. Some notice a difference immediately; others do not notice a difference at all. All of those experiences are valid, and none of them prove or disprove any claim about frequencies.

Our view: the value of retuning, if there is value for you, comes from the intentional act of listening — slowing down, choosing a sound on purpose, paying attention. Any frequency you choose, including standard 440 Hz, can support that kind of attention.

We do not recommend any particular tuning

Re-Tuner does not recommend 432 Hz over 440 Hz, Solfeggio frequencies over standard tuning, or any one frequency over any other. We write about them so you can make your own informed choice, and we link to apps so you can try them yourself. The choice is yours.

Our role: tools and information

Re-Tuner is an independent directory and set of guides. We link to apps built by various developers — including SYQEL and others — so you can retune music if you want to. We do not control those apps, their pricing, their features, or their claims. Each app has its own terms of service, privacy policy, and support.

When you buy or subscribe to any linked app, you are entering a relationship with that app's developer, not with Re-Tuner.

Historical and cultural information

Sections of this site describe historical musical practice (Verdi tuning, Baroque pitch standards, Gregorian chant, the Solfeggio tradition, etc.) and modern sound-healing culture. We present this material as cultural, historical, and philosophical context — not as medical or scientific truth.

Conspiracy claims about the origins of A440 (Nazi, Rockefeller, etc.) are discussed because they are widely circulated, not because we endorse them. We note where the historical record does and does not support them.

Personal experience varies

How a frequency "feels" is a subjective experience shaped by the song, your mood, your environment, your beliefs, your attention, and many other factors. Testimonials and personal experiences described on this site — our own or others' — are not evidence that you will have the same experience.

External links

We link to third-party apps, articles, and research. We do not control those sites and are not responsible for their content, their accuracy, their claims, their pricing, or their changes over time. External links are provided for convenience and do not imply endorsement of everything on the linked site.

No guarantees

We do not guarantee any specific outcome from using any app, listening to any frequency, following any practice described on this site, or reading any article here. The information on this site is provided "as is" without warranty of any kind.

Changes

We may update this disclaimer at any time to reflect changes in the site, the apps we link to, or our understanding. The current version is always the one at this URL.
