I've long believed intuitively that musical training enhances people's ability to learn other things and process the world more sensitively, and there certainly is research out there to back that up in terms of mathematical and other analytical thinking, but these new findings are really amazing. Scientists at Northwestern (my alma mater, go cats) have found that people with musical schooling are more sensitive to the emotional content of sounds, including speech of all kinds. Key graph from the article at PhysOrg.com:
In essence, musicians more economically and more quickly focus their
neural resources on the important -- in this case emotional -- aspect
of sound. "That their brains respond more quickly and accurately than
the brains of non-musicians is something we'd expect to translate into
the perception of emotion in other settings," Strait says.
The implications range from being alert in a business meeting to responding to a child to communicating with one's mate. Is there anything more important in human relations than sensitivity to emotional overtones and subtext? Is there any better way to develop the parts of the brain that handle that subtle information? It's just more evidence that music is far far more than just pleasing sound.
