The influence of different musical modes and tempi on time perception

Studies involving the interaction between musical mode and tempo on time perception have been carried out through comparisons between a single major mode and a single minor mode, presented in different tempi. However, classifying the modes only into major and minor has not been considered sufficient. The purpose of this study was to verify the influence of the musical mode and tempo interaction on time perception analyzing the effect of different modes performed in the slow, moderate and fast tempi. Fifty undergraduate students of both sexes individually listened to 12 musical excerpts (4 modes - Ionian, Mixolydian, Dorian and Aeolian - and 3 tempi - 72 bpm, 114 bpm, and 184 bpm), one excerpt at a time. After each excerpt, the participants performed a time-reproduction task, in which they had to press a button (beginning of the task), recal the duration of each excerpt and press a button again (end of the task). Results showed no interaction between mode and tempi and no differences between musical modes, regardless of tempo. However, regardless of the mode, excerpts in slow tempo was judged shorter than in moderate and fast tempi, respectively, and excerpts in moderate tempo was judged shorter than excerpts in fast tempo. These results can contribute to understanding the psychological processes of attention, memory and expectancy related to the perception of time in music listening situations.
