The impact of music has been studied, and there is a growing body of evidence according to which playing a musical instrument has a positive impact on academic achievement in school. It is important for music teachers to know how to support students’ motivation to learn music. A person can be motivated in intrinsic or extrinsic ways, and the motivation to learn is revealed in learning activities expressed as learning engagement. However, a different perspective on engagement raises the question of how to be coherent with the data presented in the studies. As early engagement predicts future levels of engagement, this paper presents an integrative review that explores learning engagement in preschool and primary school music lessons and identifies that more research is needed in this area of learning engagement in music.
