Music Medicine: Sound At A Cellular Level | Dr. Lee Bartel | TEDxCollingwood
This is very interesting. I was waiting to see if he'd talk about 432 or 528 Hz as I used both 24 hours a day for the last 2 or 3 weeks of my wife's life. She really liked the 528. The 432 interested me because before about 1880 that was the frequency of A. The 440 we use today produces aggression.
