In contemporary virtue ethics, virtues are often assimilated to skills. This assimilation suggests that the moral knowledge of virtuous individuals parallels the practical knowledge of experts in a particular skill. According to Julia Annas (2011a, 2011b), virtues function as skills requiring the ability to articulate reasons for one’s actions. These skills are developed through habitual practice over time. For example, a pianist who internalizes piano techniques possesses practical expertise akin to someone who understands their actions, even when performed automatically. Annas (...) argues that to cultivate ethical virtue, we should emulate musical action, viewing it as a habit rather than mere repetition. This analogy aids in understanding virtue acquisition as practical skill-building. Expanding on Annas’s insights, this article contends that musical practice offers profound ethical implications for musicians as potential moral agents. Supported by important neurological and psychological studies on musical expertise, as well as the dynamics of classical music interpretation and professional career development, this argument sheds light on the ethical dimensions of musical agency. These insights into musical expertise could enhance our understanding of ethical expertise overall. (shrink)
