<i>On the Sensations of Tone as a Physiological Basis for the Theory of Music</i> is a seminal work in the field of music theory. The book deals primarily with acoustics and the human perception of sound as the basis for all musical theory. The book is divided into three major parts, detailing the scientific composition of vibrations, the interruption of harmony, and the relationship of musical tones. This is a highly technical work that deals significantly with physiological responses to sounds. The book combines text, illustrations, charts, figures, and sheet music to illustrate its point and concludes with a detailed index, allowing this volume to serve as a reference document.<br><br>Helmholtz's work in <i>On the Sensations of Tone as a Physiological Basis for the Theory of Music</i> is the stuff of genius. This text has been foundational for the further study of music theory, and is still considered a must-read text by many academics.<br><br><i>On the Sensations of Tone as a Physiological Basis for the Theory of Music</i> is one of the most important works ever written on the subject of tone and music theory. Hermann Helmholtz expertly combines his knowledge of both music and physiology to create a text that remains invaluable to this day. This book is thus highly recommended for the studious and educated musician seeking to improve their theoretical knowledge base.
