It is becoming a wider known fact that music education contributes not only to increased intelligence or test scores, but also actively impact brain development. The fact is music is an important avenue to individual success.
Researchers found that children given piano lessons significantly improved in their spatial- temporal IQ scores (important for mathematical reasoning) compared to children who received computer lessons, casual singing, or no lessons. -Rauscher, F.H., Shaw, G.L., Levine, L.J., Wright, E.L., Dennis, W.R., and Newcomb, R.
Researchers in Leipzig found that brain scans of musicians showed larger planum temporale (a brain region related to reading skills) than those of non-musicians. They also found that the musicians had a thicker corpus callosum (the bundle of nerve fibers that connects the two halves of the brain) than those of non-musicians, especially for those who had begun their training before the age of seven. – Schlaug, G., Jancke, L.,
A University of California (Irvine) study showed that after eight months of keyboard lessons, preschoolers showed a 46% boost in their spatial reasoning IQ. – Rauscher, Shaw, Levine, K. and Wright, “Music and Spatial Task Performance: A Causal Relationship,” University of California, Irvine.
