=CATECHESIS; OR, CHRISTIAN INSTRUCTION PREPARATORY TO CONFIRMATION AND FIRST COMMUNION.= By CHARLES WORDSWORTH, D.C.L., Bishop of St. Andrew’s. New Edition. Small 8vo. 2s. =A THEORY OF HARMONY.= Founded on the Tempered Scale. With Questions and Exercises for the Use of Students. By JOHN STAINER, Mus. Doc., M.A., Magdalene College, Oxford, Organist to St. Paul’s Cathedral. Royal 8vo. 7s. 6d. “_It is the first work of its class that needs no apology for its introduction, as it is really much needed especially by teachers, who would fail without the aid of its principles to account for many of the effects in modern music, used in direct opposition to the teaching of the schools. It is difficult, if not impossible, to give a more elaborate description of a book destined to effect an entire change in musical teaching without entering into details that could not but prove uninteresting to the general readers, while to the musician and amateur, the possession of the book itself is recommended as a valuable confirmation of ideas that exist to a large extent in the minds of every one who has ever thought about music, and who desires to see established a more uniform basis of study. The great and leading characteristic of the work is its logical reasoning and definitions, a character not possessed by any previous book on the subject, and for this Dr. Stainer’s theory is certain to gain ground, and be the means of opening an easy and pleasant path in a road hitherto beset with the thorns and briars of perplexing technicalities._”――MORNING POST. “_Dr. Stainer is a learned musician, and his book supplies a manual of information as well as a rich repository of musical erudition in the form of classical quotations from the great masters._”――JOHN BULL. “_Dr. Stainer, in his thoughtful book, sees clearly of amalgamating opposing systems in order to found a theory of harmony. He bases his work on the tempered scale, and he developes and illustrates his theory by questions and exercises for the use of students. His opening exposition of the rudiments of music is clear: when he reaches the regions of harmony he comes on debateable ground._”――ATHENÆUM. “_To the student perplexed and chained down by the multitudinous rules of the old theorists, we cannot give better comfort than to advise him to read forthwith Dr. Stainer’s ingenious and thoughtful book. It is exceedingly well got up, and from the clearness of the type used, very easy and pleasant to read._”――CHOIR. =CHURCH ORGANS=: their Position and Construction.
