Another great factor in modern European thought with which I would attempt to correlate music is the factor of religion. No one will deny that the last generation has seen profoundly important changes in religious thought: whatever may have been the eddies and backwaters, the main stream has run, and still runs, like a cataract. These changes may be very differently judged by different types of men, all of them equally firm believers in the supremacy of spiritual ideals: some may definitely regret, some may, with the help of such conceptions as that of progressive revelation, steer a middle course, some (among whom I would number myself) may definitely welcome. But in whatever light we may regard these radical refusals of the old allegiances, we shall naturally expect to find their influence in music, which has had in many ways so intimate a connexion with religion. Indeed, the conception of music as in some special way the handmaid of religion dies very hard. It is still possible, in April 1919, for distinguished musicians, when appealing for funds for the foundation of a professorship of ecclesiastical music, to put their names to the statement that 'the church will always be the chief home and school of music for the people'[71]: and this when the facts about attendances at places of worship have long been familiar. We must rate the influence of church music more modestly; it has a great influence in its own sphere, but its sphere is only one among many.
We may, I think, envisage this religious development on its practical side as a process of differentiation by which the sincere standers in the old and the middle and the new paths have little by little drawn apart intellectually--but not, in societies that are happily able to take broad views of human nature, otherwise than intellectually--not only from each other but still more from those who, whatever their ostensible labels, are in reality followers of Gallio and routine. And something like the same process is observable in the religious music of the past generation. Many of its old conventions have silently dropped away, unregarded and unregretted: whatever the outlooks, and they are many and various, they are more clear-sighted, more sincere. Here in England we have somewhat lagged behind: we have had, not perhaps altogether fairly but indubitably, a reputation for national hypocrisy to sustain, and our religious music has only with difficulty shaken itself loose. Not very long ago, Saint-Saëns's _Samson and Delilah_, now one of the most popular of operas, could only be performed as an oratorio: it dealt with biblical incidents and characters, therefore it was religious music, therefore it could not be given stage presentation. Of course this kind of attitude is never logical: for a long time we closed Covent Garden to Strauss's _Salome_ for the same reason, but no one, so far as I know, ever proposed to endow it with a religious halo. Now, when Sunday secular music is everywhere, its origins seem lost in antiquity; but the chamber-music concerts at South Place in London and Balliol College in Oxford, which are, I think I am right in saying, the twin pioneers, are both little over thirty years old. In most other countries, however, music has suffered far fewer checks of this kind; and it is of more importance to correlate musical and religious development on more general lines. Particularly interesting, I think, is the history of the decline of the oratorio, which I should myself be inclined to date from the production of the German Requiem of Brahms about half a century ago, though the real impetus has become apparent only during the last generation.
