Very prolific Baroque composer. Composed a large number of concerti, inspiring Bach to the same form. He composed much of his work for the orchestra at the girl’s orphanage in Venice where he was music master.
His most famous work is undoubtedly the Four seasons, four violin concertos depicting natural scenes in music,  but his flute concerto La Notte is also well-known and very good listening.

In the Four Seasons, which had four violin concertos depicting natural scenes in music. While three of the concerti are of original conception, the first, "Spring", borrows motifs from a Sinfonia in the first act of his opera "Il Giustino," composed the same time of the Four Seasons. The inspiration for them was probably the countryside around Mantua. They were a revolution in musical conception: in them Vivaldi represented flowing creeks, singing birds (of different species, each specifically characterised), barking dogs, buzzing mosquitoes, crying shepherds, storms, drunken dancers, silent nights, hunting parties (both from the hunter's and the prey's point of view), frozen landscapes, children ice-skating, and burning fires. Each concerto was associated with a sonnet of Vivaldi's hand, describing the scenes depicted in the music. They were published as the first four of a collection of twelve, Il cimento dell'Armonia e dell'Inventione, his Opus 8, published in Amsterdam by Le Cène in 1725.
