Why we built this
Alternative tuning is one of the most-discussed and least-explained topics in modern music culture. "432 Hz" and "528 Hz" show up in millions of YouTube uploads, Spotify playlists, and meditation apps — and most of the information around them is either dismissive (treating it as pseudoscience) or wildly over-claimed (treating a sound as a cure).
We wanted a plain, grounded middle path: a place that explains what retuning is, where the ideas come from, what we actually know, what we don't, and — most importantly — the practical tools you can use to retune your own music so you can decide for yourself.
What we are
- An educational guide. The Start Here series walks through Solfeggio frequencies, the 440 Hz standard, Verdi tuning, pure tones vs retuned music, and how retuning actually works — honestly and without hype.
- A directory of retuning apps. We link to apps built by developers (including SYQEL and others) that let you retune your music on whatever platform you listen on. We don't build those apps ourselves; we help you find the right one.
- A finder quiz. The 60-second finder maps your listening habits to the right app in three or four questions.
What we are not
- Not a medical or wellness site. We do not diagnose, treat, cure, or prevent any condition. We don't offer therapeutic advice. See our full disclaimer.
- Not advocates for any particular tuning. We write about 432 Hz, 440 Hz, and the Solfeggio set so you can make an informed choice — not to convince you that one is right.
- Not the developer of the apps we link to. Each app has its own developer, pricing, support, and terms. We just help you find the one that fits.
How we write
We try to describe associations instead of making claims. If a frequency is "commonly associated with" a theme, that reflects what sound-healing frameworks say about it — not what the frequency does to you. We treat conspiracy theories about pitch standardization (Nazi, Rockefeller, etc.) honestly: common claims, not well-supported, but worth discussing because they shape the culture.
