Over two decades ago researchers in the US began studying the link between learning to read music and play the piano, and ability in Math and Science. This led to a ten year UCLA study comparing results for young students taking music versus students taking computer classes. Students learning to read music and play the piano scored significantly higher on Math and Science assessments.

Researchers have found the first evidence that young children who take music lessons show different brain development and improved memory over the course of a year compared to children who do not receive musical training.
