The results of a research project by Northwestern University, published in July 2015, suggest that music training, begun as late as high school, may help improve the teenage brain’s responses to sound and sharpen hearing and language skills.
The research indicates that music instruction helps enhance skills that are critical for academic success. The gains were seen during group music classes included in the schools’ curriculum, suggesting in-school training accelerates neurodevelopment.
Professor Nina Kraus, director of Northwestern’s Auditory Neuroscience Laboratory at the School of Communication, and her colleagues recruited 40 Chicago-area high school freshmen (14-15 years-old) in a study that began shortly before school started, and followed them until their last senior year (18-19 years old). Nearly half the students had enrolled in band classes, which involved two to three hours a week of instrumental group music instruction in school. The rest had enrolled in Junior Reserve Officers’ Training Corps (JROTC), which focused on fitness. Both groups attended the same schools in low-income neighbourhoods.
All participants improved in language skills, but the improvement was greater for those in music classes, compared with the JROTC group. According to the authors of the report, high school music training might hone brain development and improve language skills. The stable processing of sound details, important for language skills, is known to be diminished in children raised in poverty, raising the possibility that music education may offset this negative influence on sound processing.
