[1] The symphony is clearly indebted to Beethoven's predecessors, particularly his teacher Joseph Haydn as well as Wolfgang Amadeus Mozart, but nonetheless has characteristics that mark it uniquely as Beethoven's work, notably the frequent use of sforzandi, as well as sudden shifts in tonal centers that were uncommon for traditional symphonic form (particularly in the third movement), and the prominent, more independent use of wind instruments.
Beethoven originally intended to dedicate the symphony to Elector Maximilian Franz, who had been forced from Bonn by the armies of revolutionary France and was staying in Hetzendorf, just outside Vienna at the time.
Due to Beethoven's metronome markings and the addition of the indication of con moto ("with motion"), the Andante (in F major, the subdominant of the symphony's home key) of the second movement is played considerably faster than the general concept of that tempo.
In contrast to the tradition, Beethoven uses the entire instrumentation of the orchestra (2nd flute tacet) and, consequently, displays a vast spectrum of sound in this movement which, as well, is composed in sonata form.
The third movement is on the one hand remarkable because, although it is indicated as Menuetto, it is marked Allegro molto e vivace and, consequently, to be played so fast that it is essentially a Scherzo – a description mostly used after Beethoven's first symphony.
The finale opens with another introduction consisting only of scale fragments played slowly by the first violins alone (an unusual effect) beginning on G and gradually adding more notes.
Composed again in a solid sonata form, Beethoven uses the scale as the prevailing motivic element in this movement which, by character, pays most of all tribute to the customary finale established by Haydn in the preceding decades.
Therefore, Beethoven introduced himself with this work uniquely and boldly as an advancing symphonic composer and stood true to this statement throughout his compositional life.
