This book provides study material, in English, for the development of a thorough and reliable organ technique based on historical principles and tradition, toward the development of expressiveness and stylistic differentiation. A central theme is the ergonometric aspect of organ playing. A major essay, “The Coherence between Musical Expression and Organ Technique,” comprises the first of two parts of the book. The second consists of many technical exercises with comments. This material is primarily intended for those with a relatively advanced keyboard technique.
