Mozart effect? Nope, it’s the “Sing with Real People” effect! In music classes, yes, children are being exposed to many different kinds of music. But most importantly, they are interacting with their caregiver, and the caregivers are learning many different ways to have meaningful interactions with their children outside of class. It doesn’t matter whether you are a professional musician or completely tone deaf, interacting with your children has a positive influence on so many areas of their development!
“The most important influence on early brain development is the real-life serve and return interaction with caring adults.
