Effects of music on physiological measurements and mood states, and their correlation with impression of the music Author: Momose Keiko 1//Fujisawa Yukihiro 2//Uchiyama Akihiko 3 Affiliation: Faculty of Information Technology, Kanagawa Institute of Technology (Kanagawa, Japan) [1]//Faculty of Engineering, Kanagawa Institute of Technology (Kanagawa, Japan) [2]//School of Science and Engineering, Waseda University (Tokyo, Japan) [3] Conference/Journal: J Intl Soc Life Info Science Date published: 2004 Other: Volume ID: 22 , Issue ID: 2 , Pages: 545 , Word Count: 133 The purpose of this study was to investigate whether music that has an unvaried impression among different persons has reproducible effects on physiological measurements and mood states. Eight subjects listened to nine pieces of instrumental music, and evaluated the degree of impression by the semantic differential method (SD method). A large standard deviation of each item was found for each piece of relaxation music, whereas deviations for pleasant and sad music were small. Then, physiological and psychological effects of pleasant and sad instrumental music with small standard deviation were measured. Results showed that (1) mood states before and after listening to music depended on the impression of the music, (2) R-R intervals while listening to music were longer than those during a rest period, and (3) R-R intervals were correlated with fatigue score of mood states.
