How many concerti grossi and conserto did vivaldi write?

Antonio Vivaldi composed around 400 concerti grossi, making him one of the most prolific composers of this genre. His concerti grossi were published in several collections, including "L'Estro Armonico" (1711), "La Stravaganza" (1713), and "Il Cimento dell'Armonia e dell'Inventione" (1725).

Vivaldi also wrote around 50 concertos, which were similar to concerti grossi but with a more prominent role for the solo instrument. These concertos included works for various instruments, such as the violin, cello, and recorder.

In addition to concerti grossi and concertos, Vivaldi composed operas, sacred music, and chamber music, including sonatas and trio sonatas. His works are known for their energy, virtuosic writing, and use of instrumental colour and texture.
