The Mass in B Minor is arguably Bach's greatest single work. This short guide considers the work from many angles, offering the reader basic information in a concise and accessible form. John Butt gives an absorbing account of the work's genesis, its historical context, and its reception by later generations. One chapter considers the work movement by movement, providing the text in both Latin and English, and the final group of chapters on the music itself suggests some new approaches to the work--its forms, style and overall structure. This is an informative and lucid guide, providing an up-to-date summary of existing research and opinions together with some new and challenging insights.
