Symphony No. 1 in C Major, Opus 21

Beethoven's Symphony No. 1 in C Major, completed in 1800, is considered a work of the mature Classical period. While it shows influences from Haydn, particularly in the finale, it is full of Beethoven's originality. The symphony features four classically structured movements, highlighting his skill in expressive woodwind writing and dynamic contrasts. The third movement, a "Menuetto," foreshadows his later, more energetic scherzos. Notably, the slow introduction to the first movement uses a technique of avoiding the tonic key to build tension, a method he would employ more frequently in his later compositions. This symphony marked an important step in Beethoven's development, moving beyond purely entertainment music towards a more profound expression of intellect and emotion.12
