Absolutely....
Music, notes,frequency all are or can be healing for the body, its organs, the mind and spirit. Have you seen the work by Hans Jenny -Cymatics? HIs work is mind blowing,have a look at the web site http://www.cymaticsource.com. How often does music make us feel good, uplifted, or even sad??? Where woud the film industry be without sound to add to the tense moments?
