When putting together albums like this, producers often cite "The Mozart Effect" as evidence of classical music's remarkable bolstering effect on IQ. While some question the relevancy of those studies, it's common sense that exposing kids to music rich in culture will start them on the road toward a greater appreciation of the world around them. BUILDING BABY'S BRAIN 4 features some of J.S. Bach's most appealing pieces. Unlike other children's classical music recordings, this album is organized into more than just nap time and playtime music. It includes merry dances, marches and even simple musical exercises originally composed as tutorials. As the father to twenty children of his own, Bach had a special connection to children. The kids who enjoy his music may or may not be smarter because of it, but their lives are certainly richer for it.
