This study investigated the efficiency of music therapy in enhancing the attention span of young special needs children. Through group musical activities-such as a “hello” song, attendance song, singing, musical games, musical storytelling, music appreciation, relaxation time and goodbye song-music can improve attention span and enhance social skills and self-expression. The purposes of the study were: (1) to improve the attention span of young special needs children through music activities; (2) to investigate the level of progress made by the subjects. The duration of the study was three months, 40 to 50 minutes once per week. The results were interpreted based on data collected via a semi-structured musical activities observation form, interviews with parents, musical activities feedback form, and researcher's activity log. Cross-comparison was conducted on the quantified data and related original documents to increase the objectivity and reliability of the research results. The research findings included: 1. In comparing the efficacy of musical activities, the storytelling enabled the greatest attention span improvement, followed by the “hello” song, attendance song and singing time. 2. The results showed that music activities enhanced the attention span of young special needs children. The parents' feedback forms also supported the results. Therefore, the findings of the study provide an important resource and reference for parents and educators.
