Inborn musicality shared in movement. Upper Left: Infant less than one hour after birth watches her mother’s tongue protrusion and imitates. Upper Right: On the day of birth, a baby in a hospital in India shares a game with a woman who moves a red ball. The baby tracks it with coordinated movements of her eyes and head, both hands and one foot. Lower: A two-month premature girl, Nasira, with her father, who holds her against his body in ‘kangaroo’ care. They exchange short ‘coo’ sounds with precisely shared rhythm.
