This Participatory Action Research (PAR) investigates the integration of informal music learning in Macau’s educational context, guided by the Model of Generative Change (Ball, 2009). Engaging the participating college students (N = 41), this study explores how learners perceive the formal–informal learning continuum (Folkestad, 2006) through the four stages of informal learning experiences: awakening, agency, advocacy and efficacy (Ball, 2009). Through multiple data collection methods and qualitative analysis, students experienced (a) autonomous learning, (b) joyful peer learning, (c) creative exploration and skill development and (d) resilience through challenges. Moreover, the study highlights the stages of awakening, introspection and critique from the students’ perspectives. Notably, a subset of students, predominantly those with prior formal instrumental training, expressed critiques concerning informal learning, predominantly regarding its perceived lack of systematic structure and foundational skills. These insights suggest a need to further embed informal music learning in Macau to foster a dynamic change towards generativity and a ‘multileveled cultural world’ (Law & Ho, 2015). The implications point to a broader pedagogical shift that values diverse learning experiences, which may enhance the development of a more adaptable, innovative and well-rounded musical skill set within the student population in Macau.
