Abstract
In this study, we aimed to develop the system that can support to cultivate elementary schoolchildren's sensitiveness in education. The system is based on "Imagination expansion effect."Imagination expansion effect is obtained by adding sound information into movie contents. This system is applied to creating movie contents for elementary school education. In this paper, we proposed an automatic music classification system as a part of automatically movie generating system. From our experimental result, we investigated feature quantities of music that is necessary in the case of classifying the music into emotion expressions.
