Although music offers various functionalities in our contemporary urban life, the potential of making music with widely available computing technologies may not be well investigated. Ambient music is a category of music that focuses on the places where people are and puts an emphasis on tone and calmness over traditional musical structure or rhythm. This study reports on an initial effort to investigate ambient music’s potential by enhancing ambient music with ubiquitous computing technologies. We have developed a prototype system named DESI (distributed embedded sound information) to realize the potential of making ambient music interactive. DESI records stereophonic sound using a piano and visual markers and then pastes the sound on everyday objects like tables and chairs. The pasted sounds construct music according to their locations. Then, we investigate the possibilities and potential pitfalls through user studies.
