This study explores the efficacy of using musical activities to enhance the character aspect of education of preschoolers in a Taiwanese school setting. The Taiwanese educational authority stipulates that character development activities should focus on the core values of caring, respect, courage, honesty, responsibility, and cooperation. Educational programs utilize musical activities to instill these understandings in children. This research used in-depth interviews with five qualified early childcare teachers who are responsible for caring for children aged 5 to 6 years old. Data derived from these interviews with teachers who participated in this study revealed six significant themes concerning the benefits of integrating musical activities into the curriculum to enhance children's interest in character development. These themes are: "Caring for Others"; "Valuing Courage"; "Cooperation"; "Respect"; "Responsibility"; and "Honesty." Overall, teachers reported that positive changes in students' social interactions and behavior are fostered when the six core personal character values are incorporated into classroom instruction. Furthermore, when musical activities are combined with character development, children are better equipped to proactively address problems in their daily lives.
