In order to investigate physical and psychological factors governing timbre of complex tones, three-frequency complex tones are synthesized on a digital computer. Subjects make similarity judgments of pairs of the complex tones and the experimental data are analyzed by Kruskal's multidimensional scaling program. The analysis of the experimental data shows the followings : (1) the absolute values of the lowest and the highest frequencies are the most important factors governing timbre, (2) from a different point of view, the mean of the logarithmic values of the lowest and the highest frequencies are also important, and these values correspond to tone height (kan-dakasa) of complex tones, and the mean of adjacent frequency ratios (or absolute dissonance) is another important physical factor governing timbre and this physical factor is closely related to consonance of complex tones.
