Carl Maria von Weber's Symphony No. 1 in C was written in 1806–1807. While not usually acknowledged as among Weber's greatest works (a fact readily admitted by Weber himself), it is a testament to the young composer's gift of melody.
Though written true to form in the classical style, the music contained in the First Symphony is undoubtedly Romantic - a trend first introduced by Beethoven in his Eroica Symphony which had premiered only the year before.
The first movement, in sonata form, opens with a four-note motif (the main theme) on full orchestra, and demonstrates Weber's flair for writing creative tunes.
