This useful little book is the outcome of the author's large experience and careful research. It is written concisely, in clear and untechnical language, and frequent references are made to such authorities as Huxley, Lennox Browne, Eberth, Carpenter, Marshall, Luschka, &c. That Herr Behnke thoroughly understands his subject no one who reads his book can doubt, and if those who wish to know the right way to sing and avoid the wrong way will carefully study this little manual they will not go far wrong. For all who are dependent on the right use of their voices for their daily bread, Herr Behnke's book will be most opportune. MUSICAL STANDARD. An excellent specimen of a familiar way of putting unfamiliar truths. MUSIC TRADES REVIEW. There are excellent reasons why singers should possess an intimate knowledge of the structure and functions of the various organs concerned in the production of the voice, and this knowledge they are likely to gain more easily and effectually from the present treatise than from any other with which we are acquainted. Mr. Emil Behnke writes in a singularly clear and lucid manner, and if his book be not exactly light, it is very interesting reading. Much of the information conveyed is invaluable. We cannot too strongly recommend the present volume to the perusal of vocal students. MUSICAL EDUCATION. After carefully reading the book we are at no loss to understand how it is that there is such a demand for it amongst the members of the musical public. The style is admirably simple and lucid, and every statement made is in accordance with the latest views on the subject held by physiologists and anatomists of acknowledged eminence. KEY BOARD. The most reasonable, practical, and common-sense work to be found anywhere. THE VOICE. This book is clear and plain, and gives just the information that every singer and speaker should have. It is the ablest and most practical treatise on the voice we have seen. THE INQUIRER. Men have set themselves to try and ascertain the actual process by which vocal sounds are produced, and thus to form a scientific basis on which to found a way of training voices. Herr Behnke, in a singularly clear and lucid manner, brings the whole subject before the reader, and, to make it readily understood by non-scientific people, gives a translation of the Greek terms used by physiologists side by side with the originals. We cannot too strongly insist upon the necessity of forming a scientific basis for teaching singing, and, indeed, for training the voice for public speaking, &c. We congratulate Herr Behnke upon the patience and perseverance with which he has pursued his investigations with the laryngoscope. MUSIC.
