From Emily Gersema with USC News:

Within two years of the study, the neuroscientists found the auditory systems of children in the music program were maturing faster in them than in the other children. The fine-tuning of their auditory pathway could accelerate their development of language and reading, as well as other abilities – a potential effect which the scientists are continuing to study.

The enhanced maturity reflects an increase in neuroplasticity – a physiological change in the brain in response to its environment – in this case, exposure to music and music instruction.

“The auditory system is stimulated by music,” Habibi said. “This system is also engaged in general sound processing that is fundamental to language development, reading skills and successful communication.”
