Located in a northern Tasmanian government primary school, this study presents the findings of an investigation into the learning behaviours of middle primary (Grade 3/4) students in a collaborative music soundscape task. Recent literature regarding music education and social development are presented and the design of the research described. Analysis of data regarding seven learning behaviours that are characteristic of collaboration are explored and findings presented with particular attention to gender and group make-up. This paper confirms earlier research in the area and highlights the role for music creation tasks in the development of a range of social skills. Whilst limited by the scope of this study, of particular note are those data regarding the functionality or otherwise of gender groupings on task outcomes and the collaborative behaviours demonstrated by participants.
