In what sense are we "born musical?" Explores the unfolding and growth of musical abilities, starting in utero and progressing through infancy and childhood. Pulling from novel neuroscience research, examines early, innate responses to music, and brain areas important for musicality. Nature-nurture interactions allow for audiation, the ability to hear sounds in our head, and culminate in the developmental abilities to sing in tune and hold a beat. We examine claims that music can boost intelligence, language development, and other cognitive skills, such as visuospatial abilities. How can parents incorporate music into their children's lives to enhance bonding, healthy attachments, and social-emotional learning? We examine such questions and review recent findings, drawing on biological, psychological, and educational perspectives to understand the importance of music in infancy, childhood, and adolescence.
