In this paper, we investigate how young children aged 2 to 5 interact with music and their family's music collections. By going into their homes, interviewing them and their parents and observing the children performing a range of music-related tasks, we explore the way that pre-school children select, interact with, and organize music. Additionally, drawing tasks were included in the visits to engage the children and allow them to demonstrate their thoughts in a concrete manner. Insights into the children's' music behaviours suggest design features for a music organizer / player for very young children.
