        Tuning the brain to language
           uning the brain to language

        Research reveals that musical rhythms matching a language’s natural beat

        can significantly enhance how the brain processes speech, strengthening
        the case for rhythm-based teaching. Gill Ragsdale explains.


                 usical  rhythm may
                 boost the processing
                 of speech in the
       Mbrain—but only when
        the rhythm matches the language,
        according to new research  from
        the Basque Center on Cognition,
        San Sebastian, Spain,  by Laura
        Fernández-Merino and colleagues.
          The positive impact of musical
        training on language learning and
        proficiency is well-documented but
        the neural processes underpinning
        this effect remain mysterious. Both
        language and music are human
        universals found in every culture
        around the world and this study
        focussed on something shared by
        both: rhythm.
          The researchers recruited 33
        bilingual Spanish and Basque
        speakers  in  their  twenties
        to see how different types of
        musical rhythms influence how
        the brain “tunes in” to speech.
