 This is nothing new. Cases of using sound to achieve healing and supernatural results can be found in almost all ancient civilizations. Even today, there was much electromagnetic power in the specific instruments and sound-based rituals performed by ancient civilizations. They're not some voodoo tricks. They are pure science used by the ancients. Besides the applications of this knowledge for healing, there was also evidence of how the ancients used sound. Vibrations and frequencies to carve and levitate heavy stones and objects and use them to build megalithic structures. It's believed the Egyptians had a device that could be tuned to a specific frequency, and with it, they were able to cut massive stones, just as if they were cutting butter.
