This paper provides a discussion of how the electronic, solely IT based composition and performance of electronic music can be supported in realtime with a collaborative application on a tabletop interface, mediating between single-user style music composition tools and co-located collaborative music improvisation. After having elaborated on the theoretical backgrounds of prerequisites of co-located collaborative tabletop applications as well as the common mon paradigms in music composition/notation, we will review related work on novel IT approaches to music composition and improvisation. Subsequently, we will present our prototypical implementation and the results.     «
