The effects of music on consumers’ time perception were investigated in the context of restaurant service. The study analyzed how musical tempo affects the subjective time perception and real stay-time of customers in a restaurant. Mood state was manipulated using background music extracts pretested to vary in arousal(low, moderate, and high). Music-induced mood was found to be an antecedent on time perception such that fast tempo level contributed negatively to retrospective duration estimate, whereas slow and moderate level did positively. Diverse meal duration by different perceived service time patterns exhibited consequences of time perception.
