RESUMO
Like discourse, music is a dynamic process that occurs over time. Listeners usually expect some events or structures of events to occur in the prolongation of a given context. Part of the musical emotional experience would depend upon how composers (improvisers) fulfill these expectancies. Musical expectations are a core phenomenon of music cognition, and the present article provides an overview of its foundation in the score as well as in listeners' behavior and brain, and how it can be simulated by artificial neural networks. We highlight parallels to language processing and include the attentional and emotional dimensions of musical expectations. Studying musical expectations is thus valuable not only for our understanding of music perception and production but also for more general brain functioning. Some open and challenging issues are summarized in this article. WIREs Cogn Sci 2014, 5:105-113. doi: 10.1002/wcs.1262 CONFLICT OF INTEREST: The authors have no conflict of interest to declare.

RESUMO
The present paper reviews a set of studies designed to investigate different aspects of the capacity for processing Western music. This includes perceiving the relationships between a theme and its variations, perceiving musical tensions and relaxations, generating musical expectancies, integrating local structures in large-scale structures, learning new compositional systems and responding to music in an emotional (affective) way. The main focus of these studies was to evaluate the influence of intensive musical training on these capacities. The overall set of data highlights that some musical capacities are acquired through exposure to music without the help of explicit training. These capacities reach such a degree of sophistication that they enable untrained listeners to respond to music as "musically experienced listeners" do.

Using short and long contexts, the present study investigated musical priming effects that are based on chord repetition and harmonic relatedness. A musical target (a chord) was preceded by either an identical prime or a different but harmonically related prime. In contrast to words, pictures, and environmental sounds, chord processing was not facilitated by repetition. Experiments 1 and 2 using single-chord primes showed either no significant difference between chord repetition and harmonic relatedness or facilitated processing for harmonically related targets. Experiment 3 using longer prime contexts showed that musical priming depended more on the musical function of the target in the preceding context than on target repetition. The effect of musical function was decreased, but not qualitatively changed, by chord repetition. The outcome of this study challenges predictions of sensory approaches and supports a cognitive approach of musical priming.
