The old nature/nurture argument is dead in the water as we learn more about what affects infants in utero and even pre-in utero. No doubt, from what I have been reading, Julie's child started learning all that stuff in utero just as Mozart started learning music in utero.

Yes, Eliza, I cannot live without large quantities of SILENCE! We are very much not alone. When I lived in the deep country, and even sometimes now, I could endure town for a certain amount of time and, all of a sudden, I would get in the car and GO HOME - where I could have the silence I crave. It was not a conscious decision; I would just find myself in the car....

There is considerable research about the Mozart effect. There may be other types of music and sounds which have healing effects. I have used Gregorian Chants to soothe myself into sleep mode.
