In fine Spohr's works reveal to us a man who was deficient in personal force because he was not a creative genius, but who exerted all the influence of an original mind upon his contemporaries because he was wholly at heart and almost wholly in practice in touch with a movement new and absorbing. If Spohr had possessed real creative genius, his devotion to Mozart as a model would have dwindled before the incitements of the movement toward national romanticism which was agitating German literature and art. His yearning toward the freedom and infinite possibilities of chromatic harmonies brought him into direct conflict with the polished symmetry, the veneration for a set form and a conventional distribution of keys, of the classic period of Mozart. Had he been a man of aggressive individuality he would not have made the mistake of putting an intellectual curb on his emotional impulses, but would have spoken according to the promptings of his heart. But Spohr, though earnest in his purposes and intolerant of all that was not sincere in art, was altogether of too amiable a nature to rudely cross the Rubicon and seize upon the new territory. He was among those who saw the promised land, who felt the embrace of its atmosphere, and who yet hesitated upon the borders. The trumpet call of modern romanticism was sounded in 1821 when Vogl made Schubert's "Erl King" known to Germany, and in the same year Weber thrilled the hearts of his countrymen by giving them a national opera, "Der Freischütz," whose story, like that of Schubert's song, was taken from the folk-lore of the people. Spohr followed these leaders in making use of the national literatures as in "Faust," and the tales of the fireside, as in "Zemire und Azor"; but he emasculated his music in his endeavor to cling to the style of a period which had terminated. What might have been a style leading directly into the restless eloquence of the Wagnerian diction became a "lingering sweetness, long drawn out," and it was reserved for Weber, who had the necessary force, the resistless energy of creative power, to become the founder of true German opera and the artistic progenitor of Richard Wagner.
