What is 285 Hz used for?

285 Hz is used for rest and renewal: a reset after work, a short nap, or a quiet evening when you want to recharge. Its sound is soft and low, a step brighter than 174 Hz.
Where does 285 Hz come from?
Like 174 Hz and 963 Hz, 285 Hz was added after the original six solfeggio tones to make a nine-tone scale. It has no syllable from the old hymn; its “restore” name comes from how it's used today.
How to listen to 285 Hz
- Use a low, comfortable volume. A soft tone is easier to settle into than a loud one.
- Sit or lie down and slow your breathing to about six breaths a minute.
- Set Auto-stop for 20 minutes.
- For a power nap, lie down, close your eyes and let the tone fade out on its own.
285 Hz vs 174 Hz
174 Hz is the grounding tone, for feeling steady. 285 Hz is the restore tone, for recharging. If you can't decide, play 174 Hz for five minutes, then switch to 285 Hz.
