A beautiful visual on the impact of music education on kids’ cognitive skills — from educatorstechnology.com

Excerpt:

Does music education really improve kids cognitive skills? The answer, in our view, is hard to determine and it requires a series of longitudinal studies across different cultural and ethnic groups. However, certain small-scale studies such as the ones cited in the visual below do provide a preliminary evidence in favour of the correlation between taking music lessons and improvement in certain cognitive skills. For instance, in a study of 96 children aged 5-7 years old, those who received 7 months of supplementary music and arts classes earned higher mathematics scores than those with the schools’ typical music and arts training. In another collection of studies that involved a larger base of participants from high schools, researchers were able to identify a strong correlation between music instruction and higher reading test scores.

More specifically, the visual cites six key areas positively impacted by music education: math skills, reading skills, memory, IQ, SAT scores, and planning.
