Very good post @cob, this is a new science for me, your video explains how music works. That's very cool, because I really like the music, in general everyone is fond of music. Because in my opinion, music is a faithful friend, when we are stressed out and have many problems in the life we live, with we hear music, I feel my soul is comfortable and calm. Thanks for sharing a very helpful piece of information, and hopefully you have a wonderful day.
