In 1677 a slim quarto volume was published anonymously as A Philosophical Essay of Musick. Written by Francis North (1637-85), chief justice of the Common Pleas, the Essay is in the form of a legal case argued from an hypothesis. Utilising the pendulum as his hypothesis, North provided a rationale from mechanics for the emerging new musical practice we now call 'tonality'. He also made auditory resonance the connecting link between acoustical events in the external world and the musical meanings the mind makes on the basis of sensory perception. Thus began the modern philosophy of music that culminated with the work of Hermann von Helmholtz. As a step towards understanding this tradition, Jamie C. Kassler examines the 1677 Essay in its historical context. After assessing three seventeenth-century criticisms of it and outlining how one critic developed some implications in the Essay, she summarises the basic principles that have guided the modern philosophy of music from its beginnings in the 1677 Essay. The book includes an annotated edition of the Essay as well as the comments of the three critics.
'This is a thorough presentation of the work in hand…' Early Music Review 'Kassler's magisterial command of her subject ensures a valuable and welcome addition to scholarship on seventeenth-century English music theory and, especially, the role of music in the scientific revolution.' British Journal for the History of Philosophy 'A brilliant book.' Archives Internationales D'Histoire des Sciences 'This book certainly ought to persuade readers that the first English (i.e. vernacular) publication claiming to treat music 'philosophically' was taken seriously by the educated elite in Newtonian Britain. And like so many of Kassler's earlier publications, this study also draws attention to a wealth of material pertaining to the culture of early modern British science that most professional academics in this field have still never looked at, much less tried to understand.'
