Chirr of grasshoppers has the frequency of approx. 5000 Hz. Singing of birds – approx. 8000 Hz. In the range between them, the Water element vibrates (the sound of a sea wave, mountain stream rain...), voices of dolphins, whales, etc.
Classical Music has the same frequency. Having connected Music with the sounds of Nature, we get the most efficient medicine for restoration and maintenance of the psychical and physic health." Stepan Nederytsya
