This presentation seeks to re-examine the role of singing in classroom music lessons for students aged 13 to 14 in Singapore, emphasizing its potential to foster unity, integration, and overall well-being through the development of social-emotional and communication skills (MOE, 2025). As a universally accessible and emotionally resonant art form, singing offers adolescents a powerful medium for self-expression, empathy, and interpersonal connection.Adolescents are particularly vulnerable, grappling with heightened self-consciousness and intense peer pressure. Encouraging them to sing seems like an uphill battle. Faced with resistance and anticipating minimal returns, many teachers avoid incorporating singing into their curriculum, viewing it as too demanding with little payoff.Yet, it is widely acknowledged that singing can significantly enhance students’ overall well-being. In group singing contexts—whether through large class ensembles, small group harmonies, vocal improvisation, or lyrical interpretation—students engage in collaborative experiences that nurture emotional literacy, active listening, and both verbal and non-verbal communication.With a deep understanding of classroom realities, the Engaging with Songs (EWS) programme was developed for secondary school students. Its effectiveness lies in a tripartite partnership among professional developers, expert trainers, and schools—teachers and students alike.Based on heutagogy principles (Hase, S., & Blaschke, L. M. 2021), professional developers crafted a professional learning (PL) programme encouraging learner autonomy, capability development, non-linear learning, as well as self-reflection and self-efficacy. The content is inclusive, developmentally appropriate, and aligned with requirements for helping adolescents experience holistic growth.Expert trainers play a pivotal role by modelling vulnerability, encouraging dialogue, and fostering group cohesion. Through role modelling and the sharing of tacit knowledge, they empower teachers to explore both musical and emotional dimensions. Schools, in turn, provide the structural and cultural framework for implementation, including scheduling and institutional advocacy—ensuring students receive optimal guidance for learning and personal development.Two case studies illustrate the impact of singing-based music education across different school profiles:Case Study 1: All-Boys School (High Academic Progress)Case Study 2: Mixed-Gender School (Mixed Ability)These case studies affirm that when professional developers, expert trainers, and schools align with shared goals, singing becomes a transformative tool—not only for musical development but also for cultivating emotionally intelligent, communicative, and socially connected adolescents.
