Bach and the meanings of counterpoint - Yearsley, David (Cambridge Cambridge University Press, 2002)
This book offers new interpretations of many of Bach's late compositions which include complex musical techniques such as canon. These techniques held great significance for Bach and his contemporaries not only on account of the great skill they demanded but because of the meanings attached to them. Intricate musical devices were crucial to the Lutheran rituals of death and dying, to alchemy, to Enlightenment philosophies of stylistic change and musical progress, to musical representations of political power, and to the legacy of Bach into our own time.
