There doesn’t seem to be a physiological need for humans to have music, yet our brains seem hardwired for it. Why?
Researchers at Georgetown University Medical Centre in Washington DC looked at monkey brains in an effort to find out. They found that neurons–brain cells–are tuned to certain frequencies and harmonic sounds.
It could be that our ability to perceive music may have developed as we learned to communicate using our voice. The complex tones used in speech (and animal vocalizations, for that matter) forced our brains to evolve in such a way that our nervous systems adapted to be able to recognize and appreciate these complex tones in ways beyond just communication.
So what? Well, if they’re right, these scientists think this could mean new breakthroughs in forms of music therapy.
