The value of ensemble music-making for wellbeing is addressed in this chapter, with an emphasis on amateur musicians. Previous research on musical development over the lifespan suggests that long-term engagement might be motivated by individual wellbeing benefits. Although negative health implications are also noted, amateur musicians report fewer adverse health effects associated with musical participation compared with their professional counterparts. However, the research literature on amateur musicians has tended to focus on choir members, raising questions as to whether the predominantly positive implications of choral singing also apply to instrumental ensemble performance. Recent studies have begun to fill this research gap, but there is still uncertainty with respect to the specific factors contributing to wellbeing and health in amateur ensembles. In conclusion, tentative models to foster hypothesis-driven research are needed as well as a better understanding of the underlying mechanisms that connect long-term musical engagement and wellbeing.
