Beaulieu’s Chrestienne resjouyssance was created as an artistic weapon to harness the power of song for Protestant moral living. Thus, his collection of spiritual songs includes moral texts that offer lessons in conduct, that is, in virtue and the art of living as prescribed by a rigorous Protestant ethic. The poetic strategies utilised in this collection of contrafacta shed light on the role of song in individual moral formation and on the broader development of moral song as an emerging printed genre.
