Symphony No. 4 (Mozart)

Symphony No. 4 in D major, K. 19, is one of Wolfgang Amadeus Mozart's early symphonies. Completed in London in 1765 when Mozart was just nine years old, it is a relatively brief and straightforward work compared to his later symphonies. It is scored for two oboes, two horns, and strings.

The symphony comprises three movements:

1. Allegro: A lively and energetic movement in sonata form. It showcases the young composer's grasp of melodic development and harmonic structure, albeit in a simpler style.

2. Andante: A more lyrical and graceful movement in G major. This slower movement provides a contrast to the brisk opening and closing movements, featuring a more prominent role for the strings.

3. Presto: A quick and spirited finale, also in sonata form. This movement brings the symphony to a cheerful and satisfying conclusion.

While not as well-known or frequently performed as Mozart's later symphonies, Symphony No. 4 provides valuable insight into the development of his compositional skills and demonstrates his precocious talent at a young age. It is a significant work within the context of Mozart's early output and contributes to our understanding of the evolution of the symphony as a genre in the Classical period. The influence of composers such as Johann Christian Bach, whom Mozart met in London, can be observed in the symphony's style and structure.
