Contextual prediction modulates musical tension: Evidence from behavioral and neural responses

Tension is a bridge between music structure and emotion. It is known that tension is affected by prediction in music listening as music unfolds. Combining behavioral and neural responses, the current research investigated how musical predictions influence tension in the process of prediction build-up based on musical context (anticipatory stage) and its integration with upcoming stimuli (integration stage). The results showed that, at the anticipatory stage, compared with high-prediction conditions, in low-prediction conditions tension curve changed faster and unstable, and a larger N5 in ERP response was elicited. Furthermore, at the integration stage, compared with congruent conditions, in incongruent conditions the behavioral rating of tension were higher regardless of the predictability of the final chord; a right negativity and P600 were elicited, and the amplitude of P600 was modulated by the predictability of the final chord. These results indicated that the effect of prediction on tension was modulated by contextual predictability. The findings provide a more comprehensive view on how musical prediction affects musical tension.
