A segment of The Music Instinct featured Sheila C. Woodward of the University of Southern California, who has studied fetal responses to music. A camera and a microphone designed for underwater use were inserted into the uterus of a pregnant woman. And then Woodward sang.
The hydrophone picked up two sounds: the “whooshing” of the uterine artery and the unmistakable sound of a woman singing a lullaby.
Then something extraordinary happened. Upon hearing the woman’s voice, the unborn child smiled.
It was one of those moments that makes you catch your breath. The full humanity of the fetus could not have been clearer if he had turned to the camera and winked.
Apparently, fetal responses to music aren’t limited to smiling. They have been observed moving their hands in response to music, almost as if conducting. They have been soothed by Vivaldi and disturbed by loud tracks from Beethoven. They have even responded “rhythmically to rhythms tapped on [their] mother’s belly.”
