This paper describes the study of impressions of one minor music. The experiment invited two groups of healthy participants (one group has eight people and the other one has twenty-two), and one minor music (“Requiem (Mozart)”) is employed as the test piece. The experiment data are collected by using Visual Analog Scale (VAS) measure, and analyzed by using box-and-whisker plot, univariate scatter plot and cluster analysis. All participants are asked to listen to the minor music individually. In order to analyze their impression of the minor music, they are asked to answer the questionnaire on VAS (7 questions; “Bright-Dark”, “Happy-Sad”, and so on) individually. The results obtained from the two groups of participants are similar; they show that subjective evaluation values based on the impression of the minor music (“Sad”, “Dark”, and so on) have been obtained and visualized by the combination of box-and-whisker plot and univariate scatter plot, and it has been discovered that the questions based on the similar impression belong to the same cluster.
