Why 174 Player Plus
Built for people who own their music — and want to hear it differently.
-
A Sense of Safety
The lowest of the solfeggio tones, often described as a grounding "anesthetic" for body and mind.
-
Pain & Tension Relief
Listeners report 174 Hz as the most physically calming of the solfeggio set — useful for tension, soreness, and recovery.
-
Foundation Tone
A starting place. The frequency you reach for when you need to come back into your body.
-
Real-Time Retune
Listen to your own library at 174 Hz with one tap. No re-encoding, no waiting, no quality loss.
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.
- 01
Add your music
Point 174 Player Plus at a folder on your device — MP3, FLAC, WAV and most other common formats are supported. Your files stay where they are; nothing is uploaded.
- 02
Tap to retune
One tap and the entire library plays at 174 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 174 Player Plus
174 Hz is the foundation tone of the modern solfeggio set — a deep, low-frequency note long associated in sound healing traditions with the body, with grounding, and with what practitioners describe as a sense of safety. It's the lowest of the solfeggio frequencies and it sits at the bottom of the set for a reason: in the tradition, 174 Hz is treated as the tone you reach for when the work is physical rather than mental. Sound healers use it for pain-relief sessions, body-scan meditations, and end-of-day winding down. Many listeners pair it with deep ambient music, sleep playlists, and singing-bowl recordings.
We built 174 Player Plus because the existing tools for listening to music at 174 Hz were fiddly. If you wanted your own music retuned, you had to convert each track one at a time, end up with two copies of every album, and lose audio quality along the way. Or you had to pick one of two tunings buried in a clunky desktop app. None of them let you press play on your favourite ambient album, set 174 Hz, and just listen.
So that's what we made. Point the app at your music library — MP3, FLAC, WAV, the formats you've been collecting for years — and any track plays at 174 Hz, in real time, without altering the original file. Switch back to 440 Hz with one tap. Build playlists. Set a sleep timer. Listen offline.
The pitch is small and specific: the frequency you listen at should be your choice. You may already feel a difference at 174 Hz. You may not. Either way, the option to A/B for yourself, on the music you actually own, shouldn't cost a subscription or your listening data.
174 Player Plus is built and self-funded by SYQEL INC. The frequency-shift engine is patent-protected (US 11,836,330), real-time, and lossless. No ads. No tracking. No subscriptions. Try it free for twenty retunes, then $19.99 unlocks 174 Hz on your platform forever, or $99.99 unlocks all ten solfeggio frequencies.

FAQ
Quick questions
What is 174 Hz?
174 Hz is a low-frequency tone used in sound healing traditions as a foundation or grounding note. It's the lowest frequency in the modern extended solfeggio set, which builds on the medieval six-tone hexachord by adding three additional tones. Practitioners use 174 Hz for body-focused work — pain relief sessions, body-scan meditations, sleep practices, and any listening where the goal is to settle physically rather than activate mentally.
What is 174 Hz used for?
In the solfeggio tradition, 174 Hz is associated with the body — grounding, pain relief, the slow physical settling that happens when you stop interrupting it. Sound healers reach for 174 Hz during tuning-fork work, body-scan meditations, and sleep arcs. Many everyday listeners use it for end-of-day wind-down playlists, deep ambient music, and as a gentle accompaniment to physical recovery.
How does 174 Hz feel different from 432 Hz?
432 Hz is an alternative tuning standard for the entire musical scale — a small shift downward from the modern 440 Hz reference, used as a general-purpose alternative tuning. 174 Hz is a much deeper retune, anchored at F3 with A4 landing around 438.40 Hz. Most listeners describe music at 432 Hz as slightly warmer than the original; music at 174 Hz sounds noticeably deeper, slower, more "horizontal." Many people use 432 Hz for everyday listening and reach for 174 Hz when they want something distinctly more grounded.
What music formats does 174 Player Plus support?
We support MP3, FLAC, WAV, and other common audio formats. The app retunes in real time without re-encoding the file.
Is the app a one-time purchase?
Yes — try it free for 20 retunes, then $19.99 unlocks this frequency permanently. Want all 10? $99.99 one-time. No subscriptions, no ads, no tracking.
