How it works
Real-time retuning. No re-encoding. No quality loss.
We don't make copies of your songs. We don't apply equalization or compression. We shift the pitch of the audio stream as it plays — and that's the entire trick.

Tap to retune
One tap and the entire library plays at 963 Hz. The original files aren't touched — the retune happens in real time on the way to your headphones.
- 03
A/B as you go
Switch back to 440 Hz any time. Compare the same song side-by-side and decide for yourself. Set a sleep timer, build playlists, listen offline.
Why we built 963 Player Plus
963 Hz is the highest tone of the canonical solfeggio set — the *Si* added to the original hexachord (Ut–Re–Mi–Fa–Sol–La) in later musical theory — and in modern sound healing tradition it's the crown-chakra tone, associated with divine consciousness, with the pineal gland, and with the experience of arriving at the top of a long meditation arc. In some traditions it's called the "god frequency" or the "frequency of return."
Where the lower solfeggio tones do the work of grounding and the middle tones do the work of opening, 963 Hz sits at the closing position — the tone many practitioners reach for at the end of a long session, once the lower tones have done their work and the meditation is ready to close at altitude. Listeners describe music at 963 Hz as "still" — present with a quietness that the lower tones don't quite reach.
We built 963 Player Plus the same way we built every Player Plus app: real-time pitch-shifting of your existing music library, lossless, without re-encoding, without subscription friction. Point the app at your library. Pick 963 Hz. Listen.
The retune is patent-protected (US 11,836,330), real-time, and lossless. Original files stay untouched. Switch back to 440 with one tap. Bulk-add an album. Set a sleep timer. Listen offline.
Pricing matches the rest of the line. Free for twenty retunes, no card, no signup. After that, $19.99 unlocks 963 Hz on your platform forever, or $99.99 unlocks all ten solfeggio frequencies. No subscriptions. No ads. No tracking. We don't sell your listening data because we don't collect it.
Built and self-funded by SYQEL INC. We're a small team that prioritizes users over investors. The frequency-shifting engine is patent-protected so this option can't be quietly revoked. Whatever you bring to 963 Hz — meditation, intention, the close of a long day — we just give you the tool.

FAQ
Quick questions
What is the 963 Hz frequency?
963 Hz is the highest tone of the modern solfeggio set — the *Si* (or *Do*) that extends the medieval six-tone hexachord into the modern seven-tone form. In contemporary sound healing it's the crown-chakra tone, traditionally associated with divine consciousness, the pineal gland, and what some practitioners call the "god frequency" or "frequency of return." Many use it as the closing tone of long meditation sessions. In musical terms, 963 Hz corresponds to the note B5 when the standard scale is anchored there, with A4 ending up at approximately 428.94 Hz.
What does 963 Hz do?
In the solfeggio tradition, 963 Hz is the crown-chakra tone — paired with closing tones in meditation, intention work, and high-altitude listening at the end of long sessions. Whether you experience anything specific is your own to discover. Technically, 963 Player Plus retunes your music in real time so the note B5 sits at 963 Hz, with A4 landing around 428.94 Hz, without altering the original files.
Why is 963 Hz called the god frequency?
The phrase "god frequency" appears in some contemporary sound healing literature as a description of 963 Hz — a reference to its position as the highest tone of the canonical solfeggio set and its traditional association with divine consciousness and the crown chakra. Different traditions explain it differently. We use the term descriptively because it's the phrase listeners actually search for, but we don't make any specific theological or scientific claim with it.
Does 963 Hz really activate the pineal gland?
We don't make claims about what 963 Hz can or can't do at the biological level — that's outside what a music player should be telling you. The "pineal gland" association is a popular cultural reference around 963 Hz, originating in late-20th-century sound healing literature, but we don't endorse or rely on it. What we make is a tool. 963 Player Plus retunes your music to 963 Hz in real time, with absolute audio precision, so you can listen the way you choose to. Whatever you bring to the listening — meditation, intention, simple curiosity — is yours.
Is 963 Hz dangerous?
No. 963 Hz is just a musical pitch — the same way A4 = 440 Hz is. There's nothing inherently risky about listening to music tuned to 963 Hz. As with any audio listening, mind your overall volume and take breaks if you wear headphones for long sessions.
