Daniel’s research interests include the role of music in liturgy and ceremony, especially in the sixteenth and seventeenth centuries. His doctoral thesis (and subsequent monograph) investigated the attitudes and approaches to music of the Protestant reformers in sixteenth-century Strasbourg. This involved scrutinising treatises, hymnbook prefaces, and unpublished archival material in order to improve our understanding of why music was deemed crucial by the first Protestant reformers. The thesis also addressed questions about the importance of congregational singing in Strasbourg in the dissemination of the Reformation message further afield. He has also undertaken research on the Genevan and Scottish Psalters of the Reformation, as well as the influence of late fifteenth-century preachers on the German Reformation’s stance towards music. Currently he is preparing an edition of motets from a 1539 Strasbourg publication: Cantiones quinque vocum selectissimae.
