We present a new type of wearable musical instrument called the DJammer. The DJammer brings turntable like creative functionality to the MP3 world while offering a collaborative platform for sharing the creative process over the network. It not only provides a new tool to DJs but also empowers each listener to a new type of community experience by giving them the ability to actively participate in any jam session. In essence, the DJammer changes the 1-to-n creative process to a truly n-to-n collaborative experience. This paper describes the technologies incorporated into the DJammer, and discusses the implementation of the prototype DJammer. Usage models and future enhancements are also described.
