Music lessons “grow” a child’s brain by physically altering its structure and accelerating the maturation of neural pathways, particularly those responsible for sound processing, motor control and communication between the brain’s hemispheres. These changes are a result of neuroplasticity - the brain’s ability to reorganize itself in response to intensive multisensory and motor demands.
To elaborate, researchers using MRI scans has shown that even as little as 15 months of musical training can lead to visible structural changes in a young child’s brain:
🧠Corpus Callosum: The bridge of nerve fibers connecting the left and right hemispheres of the brain becomes larger and more robust. This enhances communication between different brain regions, improving overall coordination and problem-solving.
🧠Motor Cortex: Areas of the brain that control finger movements (the precentral gyrus) show greater relative size expansion, especially in children playing instruments like the piano or violin that require high manual dexterity.
🧠Auditory Cortex: Music training accelerates the development of the auditory pathway, helping the brain process sounds, pitches, and rhythms more accurately and efficiently.
The structural “growth” translates into several enhanced cognitive abilities, often referred to as “far transfer” skills. Because music and language share similar neural pathways, music lessons can speed up language acquisition, reading skills, and the ability to detect subtle differences in speech.
Learning to play an instrument is a “full body workout” for the brain that strengthens working memory (holding and manipulating information) and increases the attention span. The pattern recognition, counting, and understanding of fractions (rhythm/meter) involved in music are directly transferable to mathematical problem-solving. Music training also improves the brain’s ability to plan, organize and complete tasks.
These neural enhances are most profound when training begins during “sensitive periods” (typically before age 7), but they can provide lifelong benefits.
