Investigation of Method for Changing Impression of Musical Piece by Changing its Tempo

Abstract

We propose a simple method that changes impression of musical piece by changing its tempo and investigate psycho-physiological effects of the method with listening experiment. In the experiment, 8 subjects listened same musical pieces with various tempi, and analysis of heartbeat and Semantic-Differential method were used. In 6 out of 10 adjective pairs, inverted-U shapes were observed, and peak tempi of them were different. Moreover, “relaxed” evaluation might be related to listener's heart rate in rest. These results suggest possibility of constructing novel media player that changes impression of musical piece.
