Jamming culture has become associated with digital manipulation and reuse of materials. As well, the term jamming has long been used by musicians (and other performers) to mean improvisation, especially in collaborative situations. A practice that gets to the heart of both these meanings is live coding; where digital content (music and/or visuals predominantly) is created through computer programming as a performance. During live coding performances digital content is created and presented in real time. Normally the code from the performers screen is displayed via data projection so that the audience can see the unfolding process as well as see or hear the artistic outcome. This article will focus on live coding of music, but the issues it raises for jamming culture apply to other mediums also.
