Sir James Jeans has used his remarkable gifts of exposition to set out all that is relevant in the science of acoustics to the art of music. He offers a simple but precise account (illustrated with well-chosen photographs and diagrams) of the anatomical origin and workings of the human ear; the nature of sound vibrations; simple tones and complex sounds; the principles and operation of musical instruments; harmony and the musical scale; the effects of music on men and animals; and the practical problems of acoustical design. Scientists who appreciate music, musicians with an interest in science and laymen who care for both, will thoroughly enjoy this book.
