Success in school and in society depends on an array of abilities. Without joining the intense ongoing debate about the nature of intelligence as a basic ability, we can demonstrate that some measures of a child's intelligence are indeed increased with music instruction. Once again, this burgeoning range of data supports a long-established base of anecdotal knowledge to the effect that music education makes kids smarter. What is new and especially compelling, however, is a combination of tightly-controlled behavioral studies and groundbreaking neurological research that show how music study can actively contribute to brain development:
* In a study conducted by Dr. Timo Krings, pianists and non-musicians of the same age and sex were required to perform complex sequences of finger movements. Their brains were scanned using a technique called "functional magnetic resource imaging" (fMRI) which detects the activity levels of brain cells. The non-musicians were able to make the movements as correctly as the pianists, but less activity was detected in the pianists' brains. Thus, compared to non-musicians, the brains of pianists are more efficient at making skilled movements. These findings show that musical training can enhance brain function. Weinberger, Norm.

* "The musician is constantly adjusting decisions on tempo, tone, style, rhythm, phrasing, and feeling--training the brain to become incredibly good at organizing and conducting numerous activities at once. Dedicated practice of this orchestration can have a great payoff for lifelong attentional skills, intelligence, and an ability for self-knowledge and expression." Ratey John J., MD.

* A research team exploring the link between music and intelligence reported that music training is far superior to computer instruction in dramatically enhancing children's abstract reasoning skills, the skills necessary for learning math and science. Shaw, Rauscher, Levine, Wright, Dennis and Newcomb, "Music training causes long-term enhancement of preschool children's spatial-temporal reasoning," Neurological Research, Vol. 19, February 1997
* Students in two Rhode Island elementary schools who were given an enriched, sequential, skill-building music program showed marked improvement in reading and math skills. Students in the enriched program who had started out behind the control group caught up to statistical equality in reading, and pulled ahead in math. Gardiner, Fox, Jeffrey and Knowles, as reported in Nature, May 23, 1996
* Researchers at the University of Montreal used various brain imaging techniques to investigate brain activity during musical tasks and found that sight-reading musical scores and playing music both activate regions in all four of the cortex's lobes; and that parts of the cerebellum are also activated during those tasks.

* Researchers in Leipzig found that brain scans of musicians showed larger planum temporale (a brain region related to some 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.

* 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, Ky and Wright, "Music and Spatial Task Performance: A Causal Relationship," University of California, Irvine, 1994
* Researchers found that children given piano lessons significantly improved in their spatial- temporal IQ scores (important for some types of mathematical reasoning) compared to children who received computer lessons, casual singing, or no lessons.

Neurological Research, 19, 1-8.
* A McGill University study found that pattern recognition and mental representation scores improved significantly for students given piano instruction over a three-year period. They also found that self-esteem and musical skills measures improved for the students given piano instruction. Costa-Giomi, E. (1998, April).

* Researchers found that lessons on song bells (a standard classroom instrument) led to significant improvement of spatial-temporal scores for three- and four-year-olds.

* In the Kindergarten classes of the school district of Kettle Moraine, Wisconsin, children who were given music instruction scored 48 percent higher on spatial-temporal skill tests than those who did not receive music training.
