IN the evolution of opera from Weber to Wagner a gap was filled by composers of but little reputation here, although their names are known to every student of the lyric stage. Heinrich Marschner (1795-1861) composed in "Hans Heiling," Berlin, 1833, an opera based on legendary material. Its success may have confirmed Wagner's bent toward dramatic sources of this kind already aroused by his admiration for Weber. "Hans Heiling," "Der Vampyr" (The Vampire), and "Der Templer und Die Judin" (Templar and Jewess, a version of Ivanhoe) long held an important place in the operatic repertoire of their composer's native land. On the other hand "Faust" (1818) and "Jessonda" (1823), by Ludwig Spohr (1784-1859), have about completely disappeared. Spohr, however, deserves mention as being one of the first professional musicians of prominence to encourage Wagner. Incapable of appreciating either Beethoven or Weber, yet, strange to say, he at once recognized the merits of "The Flying Dutchman" and "TannhÄuser," and even of "Lohengrin"—at the time sealed volumes to most musicians and music lovers. As court conductor at Kassel, he brought out the first two Wagner operas mentioned respectively in 1842 and 1853; and was eager to produce "Lohengrin," but was prevented by opposition from the court.

Meyerbeer and his principal operas will be considered at length in the chapters in this book devoted to French opera. There is no doubt, however, that what may be called the "largeness" of Meyerbeer's style and the effectiveness of his instrumentation had their influence on Wagner.

Gasparo Spontini (1774-1851) was an Italian by birth, but I believe can be said to have made absolutely no impression on the development of Italian opera. His principal works, "La Vestale" (The Vestal Virgin), and "Fernando Cortez," were brought out in Paris and later in Berlin, where he was general music director, 1820-1841. His operas were heavily scored, especially for brass. Much that is noisy in "Rienzi" may be traced to Spontini, but later Wagner understood how to utilize the brass in the most eloquent manner; for, like Shakespeare, Wagner possessed the genius that converts the dross of others into refined gold.

Mention may be here made of three composers of light opera, who succeeded in evolving a refined and charming type of the art. We at least know the delightful overture to "The Merry Wives of Windsor," by Otto Nicolai (1810-1849); and the whole opera, produced in Berlin a few months before Nicolai died, is equally frolicksome and graceful. Conradin Kreutzer (1780-1849) brought out, in 1836, "Das Nachtlager in Granada" (A Night's Camp in Granada), a melodious and sparkling score.

But the German light opera composer par excellence is Albert Lortzing (1803-1851). His chief works are, "Czar und Zimmermann" (Czar and Carpenter), 1834, with its beautiful baritone solo, "In childhood I played with a sceptre and crown"; "Der WildschÜtz" (The Poacher); "Undine"; and "Der Waffenschmied" (The Armourer) which last also has a deeply expressive solo for baritone, "Ich auch war einst JÜngling mit lockigem Haar" (I too was a youth once with fair, curly hair).
