Ask yourself how mechanical and electrical interaction can convey musical and sound meanings ? The missing part in this video is inside the brain , inside the neurons, inside the microtubules we are receiving qualitative information which is manifested in us by TIMING all informative sequences in a a form or a WHOLE .
Without this timing array of choices coming from inside the informative cosmic field informing us through the hundreds of thousand of microtubules in each neurons we will not be conscious of any meanings we will reacted as robots with no freedom to create by choosing the right timing or the right form speaking to us specifically according to our individual history. No one hear the same .
This is my informed opinion not pure science. I am a thinker not a scientist.
