Abstract
It is still in the way to make music generation system which reflects human sensitivity in various research organizations. Among systems which are studied, there are typical systems such as the system which composite music from the impression of words and the system which utilize GA. The purposes of this study are to compose several music, to cope with the sensitivity of each individual by visualizing the relationship between human sensitivity and musical structure, quantify the whole musical structure which decides the impression of music and to realize the construction of the automatic musical creation system which reflects individual sensitivity by the method of modeling the relationship of this structure and each individual sensitivity by Neural Network.
