When one comes beyond the "Lucia" period in operatic art, he may fairly enroll himself in the ranks of those whom Walter Pater calls "spiritual adventurers,"--those who are ready to put out on unknown seas of art experience and who are notable for their active mistrust of the teachings of their grandfathers. Some of these are fools, but this fact only serves to remind one of a wise saying of that very wise man, Robert Louis Stevenson: "Shelley was a young fool, and so are these cock-sparrow revolutionaries. But it is better to be a fool than to be dead. It is better to emit a scream in the shape of a theory than to be entirely insensible to the jars and incongruities of life and take everything as it comes in a forlorn stupidity." It is seldom that men take things as they come in music in this "forlorn stupidity," for they set themselves stubbornly against the new. Yet the attitude of those who sit in amiable comfort at performances of "Lucia" and who go away saying, "Now that's the kind of music I like," with a tremendous accent on the "I,"--an accent which is plainly the thank-offering of the Pharisee,--they are surely insensible to the jars, if not to the incongruities, of the modern musical world. And the spiritual adventurers will presently say to them: "We are at the parting of our ways. Linger you, if you will, in the valley with your Donizetti and his three-four ditties and his big guitar. We are for the mountain with Wagner and Tschaïkowsky and the thunder-storms." But perchance it may occur to you to question whether they are not happier in their serene movelessness than those who are continually scaling heights. There is even some doubt about this, for they experience occasional twinges of discomfort when they hear of persons enjoying exclusive satisfaction in such works as "Falstaff" or "Otello" or "Die Meistersinger," which are to them poppy and mandragora. But there is something more pitiable than this in their sad state. That is their inability to enjoy the classics of the musically progressive.
