Abstract
The purpose of this paper is to present Robinflock, an algorithmic system for automatic polyphonic music generation to be used with interactive systems targeted at children. The system allows real time interaction with the generated music. In particular, a number of parameters can be independently manipulated for each melody line. The design of the algorithm was informed by the specific needs of the targeted scenario. We discuss how the specific needs of the polyphony with children influenced the development choices. Robinflock was tested in a field study in a local kindergarten involving 27 children over a period of seven months.
