This volume attempts to encapsulate the History of Italian Organ music from the start of the 1500s. This is the 1960 2nd edition which has been revised and substantially extended. Author, Knudd Jeppesen, uses two Italian works to analyse the styles and features of this Italian music, and presents a valuable resource and reference.
The contents of Book 1 include a history of the instrument- the origins and how it was constructed by the renaissance instrument builders. With a section of examples of fine works from this period and a guide to reading older forms of notation.
