Musical criticism has been well represented by Friedrich Rochlitz (1770–1808), the founder of the “Allgemeine Musikalische Zeitung” of Leipsic; Adolf Bernhard Marx (1799–1866), one of the most broadly educated musical writers of his time; Gottfried Weber (1779–1839), editor of the musical periodical, “Cæcilia”; Thibaut, whose “Purity in Musical Art” is a highly esteemed essay; Schumann, the composer, who gave a new and higher direction to musical criticism in his “Neue Zeitschrift für Musik.” Schumann’s gifted poetical nature is revealed in his critical reviews as well as in his music, and he set an example followed by others, though at a distance, among whom Eduard Hanslick, of Vienna, is perhaps the most worthy of mention; Wilhelm Tappert, the editor of the “Allgemeine Deutsche Zeitung,” is a zealous partisan of Wagner. His “Wagner Lexicon” is a curious compilation of all the slang and abuse that have been hurled at the composer and his friends. Among the imaginative writers on musical subjects, the most remarkable was Ernst T. R. Hoffmann, whose romantic tales have given him a prominent place in German literature. He was composer, poet, singer, teacher, conductor and theatrical manager; he was especially gifted as an improvisator. Everything this eccentric genius did, he did well. Among his works are eleven operas and two symphonies. Schumann was much influenced by the fantastic tales of Hoffmann. His “Kreisleriana” was suggested by Hoffmann’s fragments of the imaginary “Kreisler the Kapellmeister.” Beethoven wrote a humorous canon addressed to Hoffmann, and Weber loved him. [Illustration: VIENNA OPERA HOUSE From a photograph. ] Germany, during the present century, has produced almost endless works on musical theory and speculation. The most prominent representatives are G. Weber; Hauptmann, whose “Harmony and Metre” is a profound work; Marx and Lobe, whose general systems treat of all branches of musical composition, including instrumentation, and are valuable as books of reference; E. F. Richter and Jadassohn, whose treatises on harmony, counterpoint and fugue are excellent text-books. Other well-known theoretical writers are Weitzmann, Paul, Sechter, Riemann, Friedrich and Heinrich Bellermann and Westphal. [Illustration: THE CONCERT HALL IN THE GEWANDHAUS IN LEIPSIC.
