Experiments were carried out on the pitch of two groups of computer-generated complex tones. The sequence of the ten complex tones in group A are perceived as an endless scale when they are heard repeatedly (Shepard, 1964). Complex tones in group B were synthsized by slight modification of frequency structure of complex tones in group A. The experimental results were analyzed by eij-type quantification theory. The configuration of ten complex tones in group A is considerably circular. On the other hand, the configuration of ten complex tones in group B shows a considerably onedimensional character. This difference in configuration was explained by the place cue and the time cue originated from neural activities of auditory neurons.
