The purpose of this study is to verify that the implementation of the class curriculum will effectively influence students to love and enjoy music for the rest of their lives. The specific plan to be adopted by the class; ""Let's produce a mini concert"", is one in which the author implemented as an optional subject that continues from last year. In this class, junior high school students plan and hold a mini concert for a group of elementary school students. This year, in particular, they will actually be performing with many of the younger students. The author expects that the concert will make a deep impression on the audience as well as stimulating the students eagerness for performing, thus establishing this experience as their higher eventual goal. The author aims to foster a fine sensitivity for music through this activity during which the performers will realize how wonderful audience-conscious musical expression is. The author also desires to consider the relationship between this study and the study theme of our school.
