Abstract
The technique to express the music and knowledge of a musical structure is necessary to perform music. It takes long time to people acquiring these knowledge and technology. There are few people who can perform at the level of the self-expression. I think that the user experiences while trying and erring to do in the performance and established the rule of their own way, is important for performance ability. In the installation works in this research -"cotocoto"- , is visualize the combination of input words and performance of the glockenspiel. I observed and verified that the user actually experienced the work in the exhibition, and the hypothesis was able to be proven.
