“If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration.” ― Nikola Tesla
The above should be enough for today and many to come, folks… everything in Nature, from atoms to Supernovas have their own frequency.
When I look at my almost boiling water on the stove, every morning, waiting to have my green tea, what amazes and enthralls and hooks my attention is the mandala-like “vibe” on the hot water surface, this beautiful phenomenon is a visual effect and a sound, as well.

It’s the boiling water vibration… everything has several frequencies: the vibe of joy or fear, something which gives a diffuse wave to our skin…

The Universe is possibly vibrating for eons and eons ago and so will to for eons and eons to come… waves of concentric spreading in the immensity of Zero Kelvin.
Tesla knew… like Dr. Anthony Holland, a composer, musician, and scientist, searched for years about the cancer-cells of Leukemia and exposing these cells to a definite frequency, found that more than 60% of the bad cells were destroyed.
Unfortunately, no direct exposure of cancer-patients has already been scientely explored.  
When I’m seating in my studio, listening to some good music, I feel the music with my ears and body, as well.
What happens to my body when I’m soaked in music?
I barely know and understand what happens to my mind or soul… 
I cannot imagine what sound, vibes make to my organism: is low end interacting with liver or kidney?
Please be sure I’m not saying I’m avidly listening to music or my playing my guitars to preserve my body and live forever… 
… yet, it’s absolutely true after an intense, good, pleasant listening session to my Gotorama of, say, a couple of hours, when I turn-off my audio system and go back home… well, I feel different, at least!
Not better, healed or an Highlander… be content enough to feel different –  i.e. less stressed, angry, nervous.
Same sensation I have after a bare-feet walk on a looong sand beach: Music and Walking are true-to-life activities and soul-food.
Maybe one day which I hope not too far to come, science will find that frequencies are healing… that Phythagora wasn’t wrong with his 432 Hz theories.
That we can peacefully live in good health having a diet of Ravi Shankar and Bach and John Fahey’s music.
Call me a dreamer or a visionary… always thinking and looking for a music-based, war-less world.  
I just hope so, for posterity and future of humankind.
