Plants are always playing music. The amazing sound is extracted from the plant body and edited. About 30 years ago, I encountered a device played by this plant. I got the chance to attend a research presentation by a botanist. When I listen to plant music, my brain waves go down and I feel sleepy. It is important to watch while driving a car (laugh) An organic natural sound that relaxes you so much. First of all, please listen. https://www.youtube.com/watch?v=IQnMavP9RKM
