Jay Hardesty, Drazen Bosnjak and Harris Skibell are developing tone23, a musical ecosystem where music is the primary agent defining interactions between users. Music evolves in this environment based on the musical preferences and encounters of users. Implemented at hive23 in Second Life, it creates original music variations and hybrids based on association among avatars.

Music Rooms: The hive23 environment contains three rooms. Each room is associated with a separate musical stream that is determined by the avatars currently within that room. Each avatar is “tagged” with music they have chosen from a list of musical pieces, available outside the entrance to the three rooms. When an avatar enters or leaves a room, a new sequence of musical variations is produced for that room. These variations combine and rework parts from the songs identified with those avatars then inhabiting that room.

Music Analysis and Remixing: Each musical variation embodies harmonic and rhythmic manipulations that impose musical coherence on each combination of parts drawn from the songs worn by avatars within a particular room. These manipulations introduce variety into the note structure within each part, and the contrapuntal structure across parts, in order to make each remix unique.
