We start with a population of melodies encoded genetically. This population is allowed to breed every biological cycle creating new members of the population based upon the semantics of the spatial relationship between two people moving in a large, physical space. A pre-specified hidden melody is used to select a melody from the population to play every musical cycle. The overlapping of selected melodies provides an intriguing textured musical space.
