This study attempts to enhance the understanding of a music curriculum that represents holistic and meaningful learning for young children at a developmentally appropriate practice (DAP) classroom in Taiwan. The study participant implementing DAP was selected through purposive sampling by the Classroom Practice Inventory and pilot study. A qualitative case study method was employed to understand the phenomenon and context. The result found that music curriculum activities included group teaching and free music play, and the music curriculum structure was built on duration and pitch learning. In group teaching, the activities were designed by the teacher and partially extracted from music behaviour at free play to provide children with music experiences and facilitate children's learning interests. Free music play provided children with opportunities to practice newly acquired skills, extend their learning from group teaching and spontaneously connect with other domains and personal experiences. Group teaching and free music play were reciprocally affected to make music learning holistic and meaningful. (Contains 3 figures and 3 notes.)
