Antonio Vivaldi's Four Seasons is a set of four violin concerti composed in 1723. It is probably Vivaldi's best known composition and the most frequently performed musical work in the world. It is a violin concerto in which a violin plays accompanied by a chamber orchestra. The content of each concerto is varied and evokes each of the seasons to which it relates. For example, winter is punctuated by pizzicato notes on the high strings, reminiscent of an icy rain, while summer evokes a storm in the final movement, prepared by thunder rumbling several times in the movement.
