The 1973 book The Secret Life of Plants by Peter Tompkins and Christopher Bird talks about the fascinating relationship between music and plants. Certain frequencies promote cell growth and DNA healing.
Studies have shown that Solfeggio Frequencies aid in DNA healing. This does not only mean humans! Plants receive benefits of the frequencies as well. Animals may also benefit from Solfeggio Frequencies, as everything is vibrational matter, and there are most likely many ways frequencies effect everything around us that we have not discovered yet.
There are no major downsides to listening to Solfeggio Frequencies, so try them out with your fur friends, or green friends!
