Many natural phenomena, such as the seasons, days, breaths, and heartbeats, have a cyclic nature. The speed of a cycle is termed tempo. The tempo of background sounds has been shown to affect the speed of behavior; hearing fast-tempo sounds often results in accelerated behavior. However, the mechanism underlying this phenomenon remains unclear. In this paper, we provide a short review of the literature with a particular focus on two processes: perceptual-motor synchronization and arousal increase. Moreover, we propose that the context, i.e., whether the tempo of background sounds becomes faster or slower, is an important factor for change in behavioral speed. Possible directions for further research are discussed.
