=Weber’s personality= was pleasing; of excellent birth, his experience of the world through his positions as opera-director and his frequent concert-tours, made him an agreeable companion and a favorite in society. He was cultivated, well read in philosophy and science; he possessed considerable literary and critical ability. In consequence of his intellectual and social gifts, he was a new type of musician, who did much to improve the social status of the composer. He was a remarkable pianist, with an immense command of technic, original in style and eloquent in expression; also a forceful conductor. =Weber the Composer=.—Weber is, first of all, the composer of the three operas, “Der Freischütz,” “Euryanthe” and “Oberon,” which are discussed in Lesson XXXVII. The overtures to his operas are his best orchestral works; his symphonies and chamber-music are unimportant. However, his three concertos for clarinet and orchestra are classics in the literature of that instrument. Weber’s songs are interesting for the sidelight they throw on the development of the Folk-song tendency, but in this line he was entirely overshadowed by Schubert and Schumann. However, Weber’s piano music is exceedingly important. The concertos for piano are seldom heard, but the “Concert-piece” is still amply worth study. The piano sonatas (especially those in C and A-flat) show great technical inventiveness, melodic charm and original effects, but they are less happy in point of form. Next to the sonatas in interest comes the delightful Op. 65, “Invitation to the Dance,” so well-known in Berlioz’ orchestral version. In addition are the “Momento Capriccioso,” Op. 12, the Rondo in E-flat, Op. 62, the “Polacca Brillante,” Op. 72, the Polonaise, Op. 21. Weber did much to develop the technic of the left hand; his piano compositions are thoroughly pianistic and rank high in the music of the Romantic period.
