They found that one-year-old babies who participate in interactivemusic classes with their parents smile more, communicate better andshow earlier and more sophisticated brain responses to music. The findings were published recently in the scientific journals Developmental Science and Annals of the New York Academy of Sciences . "Many past studies of musical training have focused on olderchildren," says Laurel Trainor, director of the McMasterInstitute for Music and the Mind. "Our results suggest thatthe infant brain might be particularly plastic with regard tomusical exposure." Trainor, together with David Gerry, a music educator and graduatestudent, received an award from the Grammy Foundation in 2008 tostudy the effects of musical training in infancy. In the recentstudy, groups of babies and their parents spent six monthsparticipating in one of two types of weekly music instruction. One music class involved interactive music-making and learning asmall set of lullabies, nursery rhymes and songs with actions.Parents and infants worked together to learn to play percussioninstruments, take turns and sing specific songs. In the other music class, infants and parents played at various toystations while recordings from the popular "BabyEinstein" series played in the background. Before the classes began, all the babies had shown similarcommunication and social development and none had previouslyparticipated in other baby music classes. "Babies who participated in the interactive music classes withtheir parents showed earlier sensitivity to the pitch structure inmusic," says Trainor. "Specifically, they preferred tolisten to a version of a piano piece that stayed in key, versus aversion that included out-of-key notes. Infants who participated inthe passive listening classes did not show the same preferences.Even their brains responded to music differently. Infants from theinteractive music classes showed larger and/or earlier brainresponses to musical tones." The non-musical differences between the two groups of babies wereeven more surprising, say researchers. Babies from the interactive classes showed better earlycommunication skills, like pointing at objects that are out ofreach, or waving goodbye. Socially, these babies also smiled more,were easier to soothe, and showed less distress when things wereunfamiliar or didn't go their way. While both class types included listening to music and all theinfants heard a similar amount of music at home, a big differencebetween the classes was the interactive exposure to music. "There are many ways that parents can connect with theirbabies," says study coordinator Andrea Unrau. "The greatthing about music is, everyone loves it and everyone can learnsimple interactive musical games together.".
