Antonio Lucio Vivaldi (March 4, 1678 – July 28, 1741), nicknamed il Prete Rosso ("The Red Priest"), was a Venetian priest and Baroque music composer, as well as a famous virtuoso violinist; he was born and raised in the Republic of Venice. The Four Seasons, a series of four violin concerti, is his best-known work and a highly popular Baroque piece.

Many of Vivaldi's compositions reflect a flamboyant, almost playful, exuberance. Most of Vivaldi's repertoire was rediscovered only in the first half of the 20th century in Turin and Genoa and was published in the second half. Vivaldi's music is innovative, breaking a consolidated tradition in schemes; he gave brightness to the formal and the rhythmic structure of the concerto, repeatedly looking for harmonic contrasts and innovative melodies and themes. Moreover, Vivaldi was able to compose nonacademic music, particularly meant to be appreciated by the wide public and not only by an intellectual minority. The joyful appearance of his music reveals in this regard a transmissible joy of composing; these are among the causes of the vast popularity of his music. This popularity soon made him famous in other countries such as France which was, at the time, very independent concerning its musical taste.

Vivaldi is considered one of the composers who brought Baroque music (with its typical contrast among heavy sonorities) to evolve into a classical style. Johann Sebastian Bach was deeply influenced by Vivaldi's concertos and arias (recalled in his Johannes Passion, Matthäuspassion, and cantatas). Bach transcribed a number of Vivaldi's concerti for solo keyboard, along with a number for orchestra, including the famous Concerto for Four Violins and Violoncello, Strings and Continuo (RV 580).
