Arcangelo Corelli was an Italian violinist and composer of the Baroque era.
Nevertheless, his compositions for the instrument mark an epoch in the history of chamber music. His influence was not confined to his own country. Johann Sebastian Bach studied the works of Corelli and based an organ fugue (BWV 579) on Corelli's Opus 3 of 1689. Handel's Opus 6 Concerti Grossi take Corelli's own older Opus 6 Concerti as models, rather than the later three-movement Venetian concerto of Antonio Vivaldi favoured by Bach.
