Really looking forward to seeing some of those articles on the brain research by your brother katlaughing. Jonathan Goldman, author of "Healing Sounds", has done a lot of work with sound vibrational therapy. It's about bringing the parts of our body back in harmony that are dis-eased (vibrating to a non-harmonic frequency to the rest of the body and the etheric field), by projecting sound (using voice, tuning forks, etc.) into the dis-eased areas.
