I’m continuing with this fascinating article By Laura Lewis Brown
A study by E. Glenn Schellenberg at the University of Toronto at Mississauga, as published in a 2004 issue of Psychological Science, found a small increase in the IQs of six-year-olds who were given weekly voice and piano lessons. Schellenberg provided nine months of piano and voice lessons to a dozen six-year-olds, drama lessons (to see if exposure to arts in general versus just music had an effect) to a second group of six-year-olds, and no lessons to a third group. The children’s IQs were tested before entering the first grade, then again before entering the second grade.
Surprisingly, the children who were given music lessons over the school year tested on average three IQ points higher than the other groups. The drama group didn’t have the same increase in IQ, but did experience increased social behavior benefits not seen in the music-only group.
The Brain Works Harder
Research indicates the brain of a musician, even a young one, works differently than that of a nonmusician. “There’s some good neuroscience research that children involved in music have larger growth of neural activity than people not in music training. When you’re a musician and you’re playing an instrument, you have to be using more of your brain,” says Dr. Eric Rasmussen, chair of the Early Childhood Music Department at the Peabody Preparatory of The Johns Hopkins University, where he teaches a specialized music curriculum for children aged two months to nine years.
In fact, a study led by Ellen Winner, professor of psychology at Boston College, and Gottfried Schlaug, professor of neurology at Beth Israel Deaconess Medical Center and Harvard Medical School, found changes in the brain images of children who underwent 15 months of weekly music instruction and practice. The students in the study who received music instruction had improved sound discrimination and fine motor tasks, and brain imaging showed changes to the networks in the brain associated with those abilities, according to the Dana Foundation, a private philanthropic organization that supports brain research.
Research has also found a causal link between music and spatial intelligence, which means that understanding music can help children visualize various elements that should go together, like they would do when solving a math problem.
“We have some pretty good data that music instruction does reliably improve spatial-temporal skills in children over time,” explains Pruett, who helped found the Performing Arts Medicine Association. These skills come into play in solving multistep problems one would encounter in architecture, engineering, math, art, gaming, and especially working with computers.
