A note about Apple Music

- iTunes Store purchases
- Bandcamp downloads
- Music from your computer
- Ripped CDs
- Podcast files
- Voice recordings
Does not work with
- Apple Music streaming
- Spotify downloads
- Other DRM-protected files
About 432 Hz
What is 432 Hz tuning?
Most modern music is tuned to A=440 Hz, the international standard since 1955. A=432 Hz is an alternative tuning where the A above middle C vibrates at 432 cycles per second instead of 440. The difference is roughly 31.77 cents -- subtle, but audible.
Many listeners find that music tuned to 432 Hz sounds warmer and more natural. Whether for meditation, yoga, or everyday listening -- try it and hear the difference for yourself.
Retune doesn't make health claims about frequency tuning. We make a music player that lets you listen at the pitch you prefer.
