Daniel Trocme-Latter 
The Singing of the Strasbourg Protestants, 1523-1541 [PDF ebook] 

This book explores the part played by music, especially group singing, in the Protestant reforms in Strasbourg. It considers both ecclesiastical and ’popular’ songs in the city, how both genres fitted into people’s lives during this time of strife and how the provision and dissemination of music affected the new ecclesiastical arrangement.
