Can babies tell the difference between "happy" and "sad" music? Does an infant really know whether a piece of music is in a major or minor key? Well, according to this article, the answer is yes. Although the article gives vague descriptions of what pieces are considered happy and sad, I'd love to see the list of songs that were used. I would also like to know why THIS is the type of research that is funded instead of other things. But that's just because I'm feeling cynical today.
