Times change and men change with them; an adage-that is especially applicable to musical art. But it is only the progressive teacher who changes with the times and he demands that the text books and studies for his use shall be of the most advanced character. To meet these demands, the Latest Improved Edition of this excellent work has been prepared. The long con tinued popularity of the Catechism in Europe and in this country is the test of its merit and the guarantee of the correctness of its principles; however, it needed revision, that the latest and best ideas might be introduced and the explana tions made more explicitly clear. This has been carefully done and the book is offered to the teacher and student with a feeling of confidence that it will be found a reliable and worthy assistant.
