Schools contexts can provide protective social and environmental factors that promote students wellbeing and resilience. General buffers against adversity suggest supportive peers, positive teachers and opportunities for success as a starting point for investigation. Instrumental music departments can provide prolonged and sustained proximal learning encounters that provide intense learning encounters with instrumental music teachers, collaboration with peers and extra-curricular activity in ensembles. This learning environment over six years provides a distinctive high school experience, requiring deeper investigation. This National study involved 35 schools across Victoria, New South Wales, Queensland, South Australia, Tasmania and Western Australia. It involved 3,167 students across years 7 -12 in well-established and sizeable Government and Independent schools. The student participants participated in a validated 48 item ‘What is Happening in This School’ survey (Aldridge & Ala’l, 2013). Initial Kaiser-Meyer-Olkin (KMO) and Bartlett tests assured an exploratory factor analysis deriving eight statistically significant elements. Internal consistency and factorability provided (Ca= 0.967) for overall scale, and models were inspected for interpretability, with +/- 2 factors, discerning an optimal factor fit. This presentation reports on factors of: buoyancy, peer support, rule/roles, teacher affiliation, environment satisfaction, student teacher engagement, self-esteem, and confidence. Mean scores for these eight factors were correlated with the single items on resilience and wellbeing. All correlations were positive and significant. Results indicate instrumental music engagement provides a range of sustaining and impactful benefits. weekly lessons and ensemble activity with exemplary performance teachers, peer activities, and a buoyant environment contribute to esteem, pride and confidence, resilience and wellbeing. Implications point to how, in optimal conditions, instrumental music learning and music department environments enculturate impactful learning traits and inoculative attitudes towards learning adversities. The study results indicate how music department structures and expectations can provide clear goal outcomes, and sustained, personalised teaching and goal orientations, amidst a learning environment that threads individual and collective, musical and social, and aspirational goal setting with tools and confidence to achieving them.
