Honing (2018) proposes the concept of “musicality” to suggest that “all humans share a predisposition for music” and that “we can all perceive and enjoy music.” This study examines “musicality” in the context of early childhood music education, with a particular focus on “Five Fundamental Constraints on Theories of the Origins of Music” (Merker et al., 2018). The aim is to consider how the guidance of caregivers and teachers can “constrain” children’s “musicality” and to provide suggestions for teaching that supports children’s musical expression. The perspective that children’s musicality is constrained by the guidance of caregivers and teachers can provide practitioners with “constraints” as frameworks to reflect on and qualify their activities.
