event worthy of special commemoration. Its first complete production in the United States was at Bethlehem, Pa., in the spring of 1900. It is enough to say of this work here that all Bach’s powers as fabricator of intricate design, and as master of all the shades of expression which the contrapuntal style admits, are forced to their furthest limit. So vast is it in scale, so majestic in its movement, so elemental in the grandeur of its climaxes, that it may well be taken as the loftiest expression in tones of the prophetic faith of Christendom, unless Beethoven’s Missa Solemnis may dispute the title. It belongs not to the Catholic communion alone, nor to the Protestant, but to the Church universal, the Church visible and invisible, the Church militant and triumphant. The greatest master of the sublime in choral music, Bach in this mass sounded all the depths of his unrivalled science and his imaginative energy. There is no loftier example in history of artistic genius devoted to the service of religion than we find in Johann Sebastian Bach. He always felt that his life was consecrated to God, to the honor of the Church and the well-being of men. Next to this fact we are impressed in studying him with his vigorous intellectuality, by which I mean his accurate estimate of the nature and extent of his own powers and his easy self-adjustment to his environment. He was never the sport of his genius but always its master, never carried away like so many others, even the greatest, into extravagancies or rash experiments. Mozart and Beethoven failed in oratorio, Schubert in opera; the Italian operas of Gluck and Händel have perished. Even in the successful work of these men there is a strange inequality. But upon all that Bach attempted—and the amount of his work is no less a marvel than its quality—he affixed the stamp of final and inimitable perfection. We know from testimony that this perfection was the result of thought and unflagging toil. The file was not the least serviceable tool in his workshop. This intellectual restraint, operating upon a highly intellectualized form of art, often gives Bach’s music an air of severity, a scholastic hardness, which repels sympathy and makes difficult the path to the treasures it contains. The musical culture of our age has been so long based on a different school that no little discipline is needed to adjust the mind to Bach’s manner of presenting his profound ideas. The difficulty is analogous to that experienced in acquiring an appreciation of Gothic sculpture and the Florentine painting of the fourteenth century. We are compelled to learn a new musical language, for it is only in a qualified sense that the language of music is universal. We must put ourselves into another century, face another order of ideas than those of our own age. We must learn the temper of the German mind in the Reformation period and after, its proud self-assertion, led to an aggressive positiveness of religious belief,
