In this project, pieces of music, interactive musical art, media art including music or sound, sound art with computer were researched in London, Vienna, Linz, Innsbruck, Paris, Tokyo, Kyoto, Nagoya. The research began with analyzing the pieces both as music and as performing art on the stage. Pieces include dance with computer sound and interactive system. Motion, form and their changing process are the expressive parameters both in dance and interactive musical pieces. But in musical pieces the motion or form and their changing process always concern about sounding or musical thinking. So it can be said that interactivity in musical pieces, even if they include interactive audio-visual system, should concentrate musical action, that is, the action of making music, i.e. playing the instruments, voicing, contacting for ensemble etc. In the interactive musical context, performing as instrument playing leads to interactive interface research, performing as voising leads to audio processing as in MAX/msp, and contacting for ensemble leads to integrating system including video effect or motion tracking as well as musical logic which enables human communication in musical pieces. Sounding aspects and communication aspects are discussed as important frameworks for today's situation of human computer interaction. The way how the music data is structured technically and semantically by mapping is reconsidered as the artistic main point in the individual piece. Four musical pieces including the original mapping ideas are examined in the viewpoints of sound gen-erating and communication.
