A notation system for distributed media art

Music, and media art in general, is often a collaborative process involving at first groups of individuals, and nowadays of computers, working together for the performance of media artworks. Interactive, intermedia scores are scoring systems which enable composers to specify temporal evolutions and variations of such multimedia systems. We will introduce a visual notation and its execution semantics for distribution of the interpretation and execution of such scores over a computer network. For instance, we will show how one can write and execute a score which specifies: part A plays on a first group of computers, followed by part B on a second group of computers, while a parallel part C containing a synchronized video effect is being played on a separate machine with dedicated video hardware. Based on the pre-existing scoring environment ossia score, we will cover how the extensions interact with the existing semantics, and present a set of small distributed scores which enables varied behaviours to be defined by the composer from our proposed set of nine temporal and three dataflow primitives for distribution
