This quintet, in A major, D667, was composed in 1819, and its title is due to the fact that the theme of the fourth movement of the variations is taken from the melody of Schubert's song "Trout," composed in 1817. The work was commissioned by Schubert and his friend Fogel, a baritone singer, when they were traveling in Northern Austria and were warmly received by B?veng?rten, and was premiered at B?veng?rten's residence. Its five movements are:

1. Lively Allegro, in A major, classical sonata form. It opens with a piano playing a triplet pattern that serves to connect the whole piece. First, the first theme of the presentation and development, and then through the section to form the E major, the piano plays the second theme, the violin repeated into the presentation section of the coda. In the development section, the violin plays the first theme in C major, accompanied by new rhythms in dotted fourths and eighths, and a fantasy chase unfolds. The recapitulation of the first theme's development pattern is reproduced by the piano in D major, ending with a short coda.

2. The cadenza, in F major, consists of three lyrical melodies. The first melody is in F major, the second in ascending f minor, and the third in D major and G major. Then the first melody is in A-flat major, the second in a minor, and the third is repeated in F major, in the tradition of Bach and Mozart.

3. Harmonic, A major. The rapid, brisk and spirited theme and the question-and-answer session between strings and piano show a witty mood. The middle section is quiet and pleasant music in the style of Viennese dance music.

4. Allegro, D major, theme with 6 variations. The theme is the song "Trout".

The theme is played on the first violin, accompanied by strings.

The first variation assigns the melody to the piano, with string arpeggios as a foil.

The second variation has the viola in the lead, and the violin in a triplet rhythm.

The third variation moves the melody to the double bass and cello, with the piano playing complex, fast passing phrases.

The fourth variation shifts to D minor in a powerful triplet rhythm.

The fifth variation is in B-flat major, which shifts to D-flat major.

The sixth variation and the ending use the wave pattern of the piano from the original song's accompaniment.

5. Allegro, A major, diatonic. The gorgeous and powerful music expresses the author's bright and broad-mindedness and love of nature during his pleasant summer travels. The music ends in a joyful mood.
