It is few that phase information is handled as a research on tone color. Because it has been thought that the phase is unrelated to the tone color. However, the result that the human can detect the phase difference is also reported, when the phase difference between each component sound of complex tone was changed. In one of the auditory sense psychological phenomenon, by the change of the harmonic composition the tone color changes, and it is not change sound pitch. This phenomenon is called "Phenomenon of the missing fundamental (MF)". As we paid attention to this phenomenon in this research, we confirmed the mechanism and examined the influence of the phase change between the component sounds to the perception of MF. As the result, it has been found that the changes of the pitch and the tone color take place in the perception by giving the phase difference. So, we concluded that not only each frequency component but also phase is largely related to a tone color.
