Schubert adapted five of his many lieders as instrumental pieces. Thus, the melody of "La Truite", lied composed in 1817, served as a theme for the variations of his quintet for piano, violin, viola, cello and double bass D 667 which remains one of the most popular works of all the chamber music. The solar tone of the piece - much more cheerful than Schubert's other chamber music works - seems to echo the happiness of the summer of 1819. Schubert composed this piece at 22 years old when he had just spent the summer in Pleasant company in Steyr, Upper Austria. This Urtext edition essentially conforms to the first Viennese edition, probably the original version of the autograph manuscript that has since disappeared. It also takes into account the only handwritten source of this work, a copy made by a friend of Schubert, Albert Stadler. Musicians will certainly appreciate the optimal arrangement of the tours!
