In order to establish an objective approach for evaluating human emotions, Emotional Spectrum Analysis Method (ESAM) has been proposed by Dr. T. Musha et al. It is possible to estimate emotion spectrums with four basic emotional states (i.e., anger/stress, joy, sadness and relaxation) by using ESAM and the measured data of brain waves. Now, we pay attention to the emotional evaluation of music sounds. More specifically, this paper describes the influence of a change of music sounds with different tones (from a minor scale to a major scale) on human emotions. The brain waves for six subjects are measured by electroencephalogram (EEG). Each emotion spectrum can be estimated by using the emotion spectrum analysis system developed by Brain Functions Laboratory, Inc. based on ESAM. The effectiveness of ESAM is experimentally confirmed by applying it to the emotion evaluation problem of the above two kinds of music sounds. We find out the possibility of ESAM for the objective evaluation in the field of music.
