"If you could give your child the gift of perfect pitch -- the ability to identify a note simply by hearing it -- would you? The few who are born with perfect pitch say notes have a concrete identity and presence, almost like colors, and being able to intuitively recognize them gives music an almost three-dimensional quality.

To put it simply, "if you taste a dish and you can name every ingredient -- that is like having perfect pitch," said pianist and music teacher Chizuko Ozawa.

It is widely accepted that you cannot learn perfect pitch as an adult. But your child, it appears, can.

Kazuko Eguchi started developing a method 40 years ago, when she was a young college music instructor frustrated both by her own lack of perfect pitch and the weaknesses she saw in her students. She attributed the problem to poor early training."
