Despite a global interest in the musical experiences of young children, the everyday musical lives of young New Zealanders remain unexamined. Using data collected through the Growing Up in New Zealand longitudinal study, we explore the early musical experiences of approximately 6,800 infants and toddlers. Data collected from the primary caregivers and their partners pre-birth, when the children were 9 months old, and 2 years old are used to explore five areas: parental singing; active musical play; music listening; involvement in music groups; and participation in wider cultural events. Musical engagement is analysed with respect to various child, parental and family characteristics, including parental education, socio-economic status, and parental knowledge of and appreciation for the arts. The results provide a holistic description of the musical environments of young children in Aotearoa New Zealand.
