Found this excellent article about Music Education and Brain Development. You need to read this.

But what transpires inside the brain (and which areas are affected) during music education? How does this early stimulation & nurturing translate into better scholastic performance? These relatively simple questions continue to be the focus of intense research efforts by developmental neurobiologists.

So let’s start our first column with the 30,000 foot and cellular perspectives. Research strongly suggests that music education causes the simultaneous and continuous stimulation of many brain regions. New connections (“wiring”) between brain cells are formed. Through ongoing music education, the wiring also benefits students in other academic domains.

Which areas of the brain are “recruited” during music education? The short answer is all major regions. Let’s review how the brain is organized and how each region is engaged during music education.
