COMPOSITION. The Four Seasons (Italian: Le quattro stagioni) is a set of four violin concertos by Antonio Vivaldi. Composed in 1723, The Four Seasons is Vivaldi's best-known work, and is among the most popular pieces of Baroque music. The texture of each concerto is varied, each resembling its respective season.t the time of writing The Four Seasons, the modern solo form of the concerto had not yet been defined (typically a solo instrument and accompanying orchestra). Vivaldi's original arrangement for solo violin with string quartet and basso continuo helped to define the form. source: Wikipedia.
