Research has been piling up over the past decade that shows [musical] training can boost everything from pitch perception to visual and motor skills.
And now a new study says it may also improve language-processing abilities – a finding that lends support to the effectiveness of teaching letters and words to kids through songs, as TV programs like Sesame Street have done
Researchers report in Proceedings of the National Academy of Sciences USA that music triggers changes in the brain stem – as well as in the cortex or outer brain layers as previously reported. Senior study author Nina Kraus says this means music training may not only improve a person’s ability to decipher different tones but also enhances reading and speech functions, because the brain stem is a pathway for both music and language.
