Brief Summary

This randomized controlled trial shows for the first time that focused musical instrumental practice as compared to traditional sensitization to music provokes multiple transfer effects in the cognitive and sensorimotor domain. Over the last two years of primary school (10-12-year-old children), sixty-nine children received biweekly musical instruction in a group setting by professional musicians within the regular school curriculum. The intervention group learned to play string instruments, whereas the control group, peers in parallel classes, was sensitized to music via listening, theory, and some practice. Broad benefits manifested in the intervention group as compared to the control group for working memory, attention, processing speed, cognitive flexibility, matrix reasoning, sensorimotor hand function and bimanual coordination Apparently, learning to play a complex instrument in a dynamic group setting impacts development much stronger than classical sensitization to music. Our results therefore highlight the added value of intensive musical instrumental training in a group setting, encouraging general implementation in public primary schools, better preparing children for secondary school and for daily living activities.

Detailed Description

This 2-year longitudinal study compared cognitive and sensorimotor development of two groups of children. Both groups received two music courses of 45 minutes per week in a class setting (maximum 20 children per class), given by professional musicians.

The intervention groups (n=34) learned to play string instruments "Orchestra in Class", the control groups (n=35) followed the standard Swiss school curriculum, with "sensitization to music" lessons, lacking focused instrumental practice.

Children who received protocolled extracurricular music lessons before or during the study, were excluded from the analyses.

The groups were compared at baseline (T0) after one year (T1) and after two years (T2) using standardized psychometric tests, evaluating cognitive and sensorimotor functions as well as tests on musicality.

Music practice, covering a wide and diverse field of skills and abilities, from sensorimotor to cognitive activities at the highest level, is a real driving force for development. Widely distributed regions in the brain, which support all these functions, are trained and better coordinated as a result of this practice. This provokes changes in the morphology and function of the brain. Consequently, practicing music regularly brings benefits that go far beyond musicality. The results of various studies indicate that children who practice music show increased verbal memory, verbal intelligence, reading, visual-spatial processing, executive functions, attention, logical reasoning, and according to some authors even better mathematics or even IQ and social skills.

Available evidence of beneficial musical practice effects on cognitive child development predominantly concerns children of parents with a high socioeconomic and educational background [10] and typically results from private lessons. Additionally, most of the time, the child is interested to learn a musical instrument, inducing a motivational bias. Evaluation of beneficial transfer effects restrains in general to a limited number of capacities or skills and randomized controlled trials (RCTs) with active control groups are scarce.

Here, the investigators compared children who intensively practiced different string instruments in a class setting within a specific Orchestra in Class (OC) program, to peers in parallel classes that received the same amount of musical instruction, also within an entire class, but lacking focused training on a complex musical instrument. Entire existing classes were assigned randomly to the OC and the Control programs (cluster randomization). The study took place in public primary schools in popular neighborhoods in the Geneva area, avoiding confounding music effects with effects of socioeconomic background.

The investigators anticipated that cognitive functions strongly involved in musical practice like working memory, attention, information processing, cognitive flexibility and abstract reasoning, as well as fine sensorimotor function would provoke enhanced positive transfer effects in the OC group as compared to the control group.
