Video: Playing music to babies is key to the development of their brains and can help their speech develop earlier, according to new research

Rock your baby in sync with music and you may wonder how the experience affects her and her developing brain.

A new study by scientists at the University of Washington’s Institute for Learning & Brain Sciences (I-LABS) shows that a series of play sessions with music improved 9-month-old babies’ brain processing of both music and new speech sounds. “Our study is the first in young babies to suggest that experiencing a rhythmic pattern in music can also improve the ability to detect and make predictions about rhythmic patterns in speech,” said lead author Christina Zhao, a postdoctoral researcher at I-LABS. “This means that early, engaging musical experiences can have a more global effect on cognitive skills,” Zhao said.
