Schubert's most famous quartet is the one in D minor with the lovely slow movement, a theme with variations, the theme being his own song, "Death and the Maiden." One of the greatest works in the whole range of chamber music is his string quintet with two violoncellos. His pianoforte trios also are noble contributions to this branch of musical art. "One glance at this trio," writes Schumann of the Schubert trio in B flat major, "and all the wretchedness of existence is put to flight and the world seems young again.... Many and beautiful as are the things Time brings forth, it will be long ere it produces another Schubert."
Mendelssohn's chamber music is as polished, affable and gentlemanly as most of his other productions, and rapidly falling into the same state of unlamented desuetude. Schumann has given us his lovely pianoforte quintet in E flat. Brahms has contributed much that is noteworthy to chamber music, and, as a rule, it is less complex and more intelligently scored than his orchestral music. Dvorak in his E flat major quartet (Opus 51) introduces as the second movement a Dumka or Bohemian elegy, one of the most exquisite of his compositions. Fascinating in his national musical tints, he was genius enough for his music to be universal in its expression; and he who used the folksongs of his native Bohemia so skillfully was no less artistic in the results he accomplished when, during his residence in New York, he wrote his string quartet in F (Opus 96) on Negro themes. Tschaikowsky and neo-Russians like Arensky, and the Frenchmen, César Franck, Saint-Saëns, d'Indy and Debussy, are some of the modern names that figure on chamber-music programs.
Songs either are strophic or "_durchcomponirt_" (composed through). In the strophic song the melody and accompaniment are repeated unchanged through each stanza or strophe of the poem; while, when a song is composed through, the music, although the principal melody may be repeated more than once, is subjected to changes in accordance with the moods of the poem.
Schubert is the first song composer who requires serious consideration. While not strictly the originator of the _Lied_, he is universally acknowledged to be the first great song composer and to have lifted song to its proper place of importance in music. Gluck set Klopfstock's odes to music; Haydn as a song writer is remembered by "Liebes Mädchen hör' mir Zu"; Mozart by "Das Veilchen"; and Beethoven by "Adelaide" and one or two other songs. Before Schubert's day this form of composition was regarded as something rather trivial and beneath the dignity of genius. But Haydn, Mozart and Beethoven at least did one thing through which they may possibly have contributed to the development of song-writing. By their freer writing for the pianoforte they prepared the way for the Schubert accompaniments.
