Scored for one flute, two oboes, and two bassoons, along with two horns in B and E and strings. Of all of Schubert's symphonies, it is scored for the smallest orchestra. It is the only one of his symphonies which does not include clarinets, trumpets or timpani as part of the instrumentation.
Mozartean influence
In character, the writing is often said to resemble Mozart; Schubert was infatuated with the composer at the time he composed it, writing in his diary on June 13 of the year of composition, "O Mozart! immortal Mozart! what countless impressions of a brighter, better life hast thou stamped upon our souls!" This is reflected particularly in the lighter instrumentation, as noted above. Indeed, the instrumentation matches that of the first version of Mozart's 40th symphony. For another example, there is a strong similarity between the opening themes of the second movement of D. 485 and the last movement of Mozart's Violin Sonata in F major, K. 377.
Musical analysis
There are four movements:
I. Allegro
\relative c'
This is Schubert's first symphony to not start with a slow introduction. What starts the movement is a four-bar structural upbeat similar to the one that begins the finale of his Fourth Symphony before the main theme starts on bar 5. The main is a simple rising arpeggio with a dotted rhythm that dominates all of the themes of the exposition. The first movement is a slightly unusual sonata form since the recapitulation begins, as in the first movement of Mozart’s sonata facile'', in the subdominant, not in the main key of the piece as is more usual. Schubert had previously used this device in his Second Symphony.
The slow movement opens with a theme in two repeated stanzas. Following that, here is a modulation to C that is very characteristic of Schubert, even at age 19. The return to the main theme is straight, passing through G minoron the way; there is a repetition of the distant modulation afterwards, though to G this time and with a more immediate return.
III. Menuetto. Allegro molto
The menuetto has the chromaticism though not the polyphony of the menuetto of Wolfgang Amadeus Mozart's Symphony No. 40. The progression used mid-way through the movement to modulate is borrowed almost directly from Mozart — using the same approach to a dominant seventh chord. The trio is quiet throughout, and only gradually accumulates instruments, beginning with only bassoon and strings, and with a subtle suggestion of a pastoral mood over held lower string notes.
