Analysis
The basic structure of the movements is similar to those of the Septet, as are many of the key relationships between the movements and principal key (E flat for the Septet, F major of the Octet). The theme of the first movement is derived from Schubert’s song Der Wanderer. The fourth movement variations are based on a theme from Schubert's Singspiel Die Freunde von Salamanka.
