So say you were at a concert....would the sounds arrange the particles in your body?
If there were loose particles in your body and the sound energy were sufficiently powerful, then yes. Human tissue is not made of loose particles and anything that might be loose inside your body is stuck to various body fluids trapping them from moving without huge amounts of acoustic energy being involved. Acoustic energy is mechanical in nature. It travels by moving air molecules. This is why sound doesn't travel in a vacuum. It needs air molecules to move around and bump into each other in order to propagate. Electromagnetic waves don't require a physical medium to travel so they can move through a vacuum. Electromagnetic waves and mechanical acoustic waves are not at all the same though. Don't confuse them or conflate the actions of one with the other.
A good example of acoustic wave energy moving particles is an ultrasonic humidifier. An ultrasonic humidifier imparts a higher than audible frequency acoustic wave energy into a piezoelectric disc by a varying electric current. That causes the piezoelectric disc to vibrate which transfers some of that energy to a shallow pool of water touching the disc. The energy is high enough in close proximity to the disc which causes very small droplets of water to break free from surface tension and become airborne. There is enough energy in the small water droplets to continue moving them for a short distance which we see as a fog coming from the humidifier machine. The water is chemically unaltered and the rest of its physical properties outside of its location are also unchanged. It's not magic nor does it require some sort of mystical metaphysics to explain it. It's just how physics works and it's very well understood.

Could that be used to help (lessen the energy needed) separate hydrogen from oxygen in hho water/hydrogen powered car systems of the hho welding systems?
I don't think so. The H-O bonds in water are chemical bonds. They need electric energy to break the bonds not mechanical energy. While technically you could vibrate the H2O violently enough to cause it to heat to the point of plasma where the bonds will separate, the amount of energy needed to do that would be insanely high and therefore extremely inefficient to the process. It takes a lot less electric energy to break the bonds via electrolysis, which is the preferred method for HHO production. For just a few volts and amps, you can make lots of HHO but to do it mechanically would be in the order of planetary-scale energy (or even higher). Better electrolysis methods are being evolved all the time so it's starting to become a highly efficient process that can't be beat easily.
Tesla used electromagnetic resonances and a guy named john keely used acoustical resonances to accomplish some of the same things.
John keely is interesting. I believe he was friends with tesla.
Electromagnetic resonance is very different from mechanical resonance. They cannot be directly compared on their capabilities just as sound and light cannot be directly compared. Sure they both involve waves of energy, but that's about all the overlap they have with each other. Electromagnetic energy is subject to quantum forces and effects which do not play any part in mechanical wave energy. Sound does not travel in packets (quanta) and electromagnetic waves do not require a medium to propagate. They are apples and hamburgers by comparison.
John Keely is widely accepted as a fraudster. His work does not stand up to scientific scrutiny. Tesla's work does, for the most part, but much of his work has been exaggerated into the realm of science fiction rather than science. His practical work is sound but his theoretical work is filled with assumption and conjecture that has been expanded on by his cult-like fans who don't really understand the physics in the first place. It's best to leave Tesla out of such discussions because there is a lot of conjecture mixed in with facts when his name comes up. It's difficult to convince a Tesla fanatic that he isn't a god and his stuff didn't always work or work like they believe it did.
No but the vibrations will vibrate you.
