While the concerto doesn't depict a specific event, it musically portrays the feelings and atmosphere of autumn. Vivaldi uses musical devices to evoke images of:
* Falling leaves: The fast, swirling movements of the strings evoke a sense of the leaves falling to the ground.
* The harvest: The slower, more melodic sections may represent the gathering of crops and the bounty of the season.
* The chill of the air: The lower register of the violin and the use of minor keys can suggest the colder temperatures of autumn.
* The coming of winter: The final movement often has a more melancholy or somber tone, hinting at the approaching winter.
So, "Autumn" is not about a specific event, but rather a musical representation of the season's atmosphere and emotions.
