A new edition of a modern classic, first published in American in 1912, which remains the most comprehensive course in canonic composition. Busoni greeted the first edition in these words: "Ziehn indicates the existence of undiscovered territory and trains young Columbuses." The book demonstrates how an extensive harmonic vocabulary embracing every kind of chord structure, may result from the control of contrapuntal lines. At a time when a growing number of music students feel the need of new disciplines in a milieu of laissez-faire, this book meets an urgent need. It will be a vade mecum for students wanting a clear and concise guide to the thorniest problems of counterpoint and will stimulate aspirant and even practiced composers. In the interests of clarity, the text has been re-set and there are innumerable music examples.1976 edition.
