The 639Hz Frequency is the "FA" cord in music and it is believed to be a key for reconnecting and stabilizing relationships between you, yourself and you among other people.
With the 639Hz sound frequency you will feel changes immediately, and by using it 3 to 5 minutes a day it will help you feel more relaxed, clear minded, and more spiritually developed. The best way to implement the effect of the frequency is by listening to it with earphones. Another option is to hear the sound frequency without earphones, as a background music (thanks to the sounds of nature combined with the 639 Hz frequency).
The application offers you four enjoyable atmospheres: Clear, Water, Fire and Nature, all combined with the 639 Hz frequency. We wish you a pleasant experience.
