Happiness can be derived from many factors in school settings, including learning and engaging with peers, being led by adult models, feelings of success through participation, or situated within environments that foster a sense of community. Whilst school music education programs can provide learning opportunities offering satisfying learner experiences, in many Primary school settings, it is rare to find developmentally sequenced, and sustainably delivered instrumental music programs. This study disseminates findings of the initial effects of commencing a daily curricular string program within an outer suburban metropolitan low SES primary school in metropolitan Melbourne, Australia. This study subject offers rare understandings of how participation in a program of this nature may impact students, their home lives, and the school community particularly within populations experiencing disadvantage. Employing a qualitative methodology to investigate various facets of impact, data were collected through semi-structured interviews conducted with Year 1 and Year 2 students (n=12), parents (n=12), teachers and administrative staff (n=3). This initial investigation focused on the participants experiences during the programme's initial induction and first year of delivery The study sought to understand possible effects on student attentiveness, dispositions to music making, and overall happiness at school and at home. The perceptions that emerged from students, parents, and staff point to the program’s structured curriculum and sustained delivery are integral to experiencing positive experiences that promotes happiness. The delivery by specialist teaching artists and a calming, mindful approach coupled with explicit group instruction resulted in generally positive attributions. Students described a mostly moderating and calming effect that promoted optimism and engagement in school life, while enhancing happiness, motivated states and aspirational thinking.These initial results provide insights into the initial impact of such a program and highlight broader educational implications for supporting happiness and mental health among young music learners within Primary education. The study contributes to the ongoing discussion regarding the positive impact of instrumental music education programs that nurture music making, enjoyment, mental well-being and resilience traits. This integrated , sustained curricular approach to music learning has the potential to strengthen success and school engagement, support regulatory functioning and coping strategies, while further promoting the integration of music practices as a way of enhancing student happiness, community, and general school achievement.
