This paper reports on a cross-cultural research study of children's preferences for group musical activities in child care centres. A total of 228 young children aged 4-5 years in seven child care centres in Hong Kong and in the Adelaide City of South Australia participated in the study. Both qualitative and quantitative data were collected via a mixed method approach. Result showed that dancing/moving was children's most preferred musical activity in centres. Significant differences were found between children's cultural contexts and their preferences for three activities: (1) Singing; (2) Listening; and (3) Playing instruments. Qualitative data further revealed the social phenomena of these two cultural contexts which influenced children's preferences. Implications for the curriculum planning of early childhood music education arising from these findings are discussed.
