The truth is, almost everything you stream is still 440 Hz — out of sync with your body’s natural resonance.
Most Frequency Music Isn’t Actually Tuned Correctly.
HZP puts the power to retune music back in your hands.
Instantly shift any song — from Apple Music, Audius, or your own library — to true 432 Hz or any Solfeggio frequency you choose.
You’ve seen “432 Hz”, “528 HZ” & “963 Hz” labels. You’ve heard the claims.
But how many tracks are actually retuned? Almost none.
HZP is the first app that lets you prove it for yourself — and fix it in seconds.
No engineering skills. No file conversions. Just pure, authentic sound you can hear and feel.

You’ve Been Listening to Music That’s Out of Tune — Literally.
For decades, most recorded and streamed music has been set to A4 = 440 Hz — a standardized pitch that disconnects sound from nature’s harmonic resonance.

The Mislabeled Myth
Playlists labeled “432 Hz”, “528 Hz”, “963 Hz” or any of the Solfeggio frequencies on YouTube, Apple Music, and Spotify are rarely verified or tuned correctly.
Most are still 440 Hz, simply renamed — because platforms don’t support frequency calibration.
The Hidden Impact
Research suggests that frequency tuning affects how we feel sound.
For example – 432 Hz often aligns with calmer heart rate, deeper relaxation, and smoother harmonic resonance — while 440 Hz can create subtle tension and restlessness.
(It’s not mysticism. It’s measurable physics.)
The Lost Connection
Before the modern concert pitch — A4 = 440 Hz — was adopted as the international tuning standard (ISO 16), music was tuned according to natural harmonic ratios. During the Baroque era, pitches varied widely: many European ensembles tuned A4 between 415 Hz and 430 Hz, depending on region and instrument type. These lower tunings were closer to the natural vibration patterns found throughout the universe.
432 Hz, in particular, aligns with the geometry of sound in nature — resonating with the Schumann Resonance and planetary orbital cycles. Similarly, 528 Hz, known as the “Love Frequency,” is associated with transformation, DNA repair, and a feeling of deep inner harmony.
Somewhere along the line, we traded harmony for convenience — and the precision of nature for the uniformity of industry.
Decades Of Trusting Blindly
Until now, there was no way to verify or correct this for yourself.
You had to trust that engineers, streaming services, or “frequency playlists” got it right.
But now, a new tool “HZ Detect” verifies that most music labeled 432 Hz, 528 Hz or other Solfeggio frequencies are actually tuned to 440 Hz!
HZP changes that.
HZP’s patented music re-tuning method if the way you can accurately re-tune any song from 440 Hz to 432 or any of the Solfeggio frequencies in real time and without any effort.
In seconds, you will be able to see, hear, and feel the truth — because you control the frequency tuning yourself.
