The Pleasure of Music: Psychological and Neurobiological Mechanisms

Music is a powerful source of pleasure in our lives although it provides no direct biological benefit as food does. This review asks how musical sounds come to be experienced as rewarding and how this pleasurable experience may influence emotion and cognition. Researches on musical perception show that the brain first represents basic features, such as pitch, maintains successive sounds in working memory, and uses learned musical regularities to form expectations about upcoming events. These perception and prediction processes can interact with general reward mechanisms, allowing abstract musical stimuli to generate rewards. Studies of biological rewards demonstrate the involvement of mesolimbic and dopaminergic systems. Music studies link pleasurable listening to reward-related brain activity, physiological arousal, and dopamine release in the striatum. Functional connectivity between the nucleus accumbens and auditory and frontal regions further suggests that musical pleasure emerges from interactions between perceptual, predictive, and reward systems. The nucleus accumbens thus serves as an important interface between cortical representations of musical structure and the assignment of reward value. Beyond immediate enjoyment, music may influence emotion regulation, stress reduction, attention, and cognitive performance. These effects vary across tasks, musical characteristics and listeners. Future applications can therefore benefit from context-sensitive and personalized approaches in learning, care settings, and music recommendation.
