Early Music Training Permanently Enhances The Brain
Over the past decade, researchers around the world have uncovered compelling evidence that formal music training, particularly for very young children, permanently improves cognitive capabilities and increases IQ scores.
In 2006, researchers studied 4 to 6 year-olds who participated in musical training using the Suzuki method over the course of a year. According to the BBC, those with training “performed better [than the control group] on a memory test also designed to assess general intelligence skills such as literacy and maths ability.”
Lead researcher Professor Laurel Trainor said, “It suggests that musical training is having an effect on how the brain gets wired for general cognitive functioning related to memory and attention.”
The actual size of music-related areas in the brain, such as the auditory cortex, cerebellum (responsible for motor coordination) and motor cortex increase with music training.
And, importantly for parents of preschoolers, according to a 2004 Scientific American article, Music and the Brain, “the extent of increase is greater the earlier the music lessons began.” These gains produce lifelong benefits: researchers at the Chinese University of Hong Kong concluded that adults who had studied music as children had improved verbal memory.
Moreover, less directly related cognitive skills appear to develop over time with music training.
Children who received at least three years…of instrumental music training outperformed their control counterparts on two outcomes closely related to music (auditory discrimination abilities and fine motor skills) and on two outcomes distantly related to music (vocabulary and nonverbal reasoning skills).
Duration of training also predicted these outcomes.
There have been a number of references to the correlation between music training and academic performance, including the College Board’s report on SAT scores where students who took courses in musical performance scored 22 points higher in Math and 28 points higher in Critical Reading and Writing (2009 data).
However, research went beyond correlation: they demonstrate a high likelihood of causality in that the control group did not see similar test gains nor changes in brain activity.
Interestingly, studies to date have not determined any particular area of the brain that specialises in music.
Rather, music appears to engage various areas of the brain responsible for other cognitive functions.
ndeed, it may be that the mental gymnastics needed to process music across multiple regions of the brain (including both hemispheres) is precisely the workout that results in the observed intellectual gains.
