In their choice of the articles of which this volume is composed the editors have given special prominence to those on the works of Sir Edward Elgar and Herr Richard Strauss, the two composers of our time who, as Johnstone considered, would bear the largest share in influencing the cause of musical development. Many of the articles were written on the first production of important works, and, in Elgar's case, further impressions are given of later performances of the same work. Those on the great acknowledged masters, if they cannot add much more to our stock of actual knowledge, are interesting as confessions of a sound musical faith. It is also true that the sum of potential energy in the works of these great masters is infinite; in this sense, that they strike a new flash out of every fresh and apprehensive mind. They can beget generations of critics, each with another thing to say. Such criticism is not a mere absorptive or passive process; it is re-creation: it puts into fresh terms, by the art of words, some of the impressions that have been built up of sound without language; or it tells those who have felt the same thing what they did not clearly know or remember that they had felt. The power to explain music is rarer than competence in judging books. It may be thought that amongst Englishmen of our generation Arthur Johnstone had as large a share as any of this re-creative genius. Musical Criticisms CHAPTER I. BACH.
