Music and speech
I haven’t read these myself, but if anyone’s interested, Aniruddh Patel does neuroscience research on the relation between music and speech. This 2003 Nature article also has a review of some cognitive science models of musical perception as they relate to testable predictions; and this article looks for correlations between linguistic and musical idiosyncracies in different cultures (specifically, if a culture’s language is “stress-timed” vs. “syllable-timed”, does the rhythm of their music reflect that?).
If you’re into music cognition, I compiled a brief list of links (starting from Patel’s publication list and a Google search, I don’t know this field) at NeuroWiki:MusicCognitionResources.
