Music and Language
Certain aspects of language and melody have been shown to be processed in near identical functional brain areas. Brown, Martinez and Parsons (2006) examined the neurological structural similarities between music and language. Utilizing positron emission tomography (PET), the findings showed that both linguistic and melodic phrases produced activation in almost identical functional brain areas. These areas included the primary motor cortex, supplementary motor area, Broca's area, anterior insula, primary and secondary auditory cortices, temporal pole, basal ganglia, ventral thalamus and posterior cerebellum. Differences were found in lateralization tendencies as language tasks favoured the left hemisphere, but the majority of activations were bilateral which produced significant overlap across modalities.
Syntactical information mechanisms in both music and language have been shown to be processed similarly in the brain. Jentschke, Koelsch, Sallat and Friederici (2008) conducted a study investigating the processing of music in children with specific language impairments (SLI). Children with typical language development (TLD) showed ERP patterns different than that of children with SLI which reflected their challenges to process music-syntactic regularities. Strong correlations between the ERAN amplitude and linguistic and musical abilities provide additional evidence for the relationship of syntactical processing in music and language.
However, production of melody and production of speech may be subserved by different neural networks. Stewart, Walsh, Frith and Rothwell (2001) studied the differences between speech production and song production using transcranial magnetic stimulation (TMS). Stewart et al. found that TMS applied to the left frontal lobe disturbs speech but not melody supporting the idea that they are subserved by different areas of the brain. The authors suggest that a reason for the difference is that speech generation can be localized well but the underlying mechanisms of melodic production cannot. Alternatively, it was also suggested that speech production may be less robust than melodic production and thus more susceptible to interference.
Language processing is a function more of the left side of the brain than the right side, particularly Broca's Area and Wernicke's area, though the roles played by the two sides of the brain in processing different aspects of language are still unclear. Music is also processed by both the left and the right sides of the brain. Recent evidence further suggest shared processing between language and music at the conceptual level. It has also been found that, among music conservatory students, the prevalence of absolute pitch is much higher for speakers of tone language, even controlling for ethnic background, showing that language influences how musical tones are perceived.

Famous quotes containing the words music and/or language:
“On the first days, like a piece of music that one will later be mad about, but that one does not yet distinguish, that which I was to love so much in [Bergotte’s] style was not yet clear to me. I could not put down the novel that I was reading, but I thought that I was only interested in the subject, as in the first moments of love when one goes every day to see a woman at some gathering, or some pastime, by the amusements to which one believes to be attracted.”
—Marcel Proust (1871–1922)
“Man acts as though he were the shaper and master of language, while in fact language remains the master of man.”
—Martin Heidegger (1889–1976)
