Instead of the discrete emotions approach adopted by Juslin & Vll (J&V), the present perspective considers musical signals as functioning primarily to influence listeners in ways that are favorable to the signaler. Viewing music through the lens of social-emotional regulation fits with typical uses of music in everyday contexts and with the cross-cultural use of music for infant affect regulation.

Deliberate practice and experience may suffice as predictors of expertise, but they cannot account for spectacular achievements. Highly variable environmental and biological factors provide facilitating as well as constraining conditions for development, generating relative plasticity rather than absolute plasticity. The skills of virtuosos and idiots savants are more consistent with the talent account than with the deliberate-practice account.

I challenge Mehr et al.'s contention that ancestral mothers were reluctant to provide all the attention demanded by their infants. The societies in which music emerged likely involved foraging mothers who engaged in extensive infant carrying, feeding, and soothing. Accordingly, their singing was multimodal, its rhythms aligned with maternal movements, with arousal regulatory consequences for singers and listeners.

I review two recent books on music, both inspired by cognitive neuroscience but differing in most other respects. Isabelle Peretz, an expert in the cognitive neuroscience of music, describes how we perceive and produce music, as reflected in neural and behavioral re­sponsiveness. Her book is intended for general readers who are interested in music and curious about the science behind our musical nature-brains that are prepared for music and changed by active musical engagement. Lynn Helding, an expert in vocal perfor­mance (...) and pedagogy, draws on findings from psychology and neuroscience to inform her approach to music learning and teaching. Aimed at musicians, aspiring musicians, and those who teach them, her book focuses largely on the means of optimizing learning and skilled performance. (shrink)
