Corelli was the creator of the concerto grosso; he combined a trio-sonata-playing group (two violins and cello), called "concertino", with a string orchestra called "ripieno". With this combination he could make contrasts of size of forces, dynamics and spatial separation as well as produce antiphonal effects.
Corelli was appointed violinist at San Luigi dei Francesi in Rome in 1713. In 1685 Corelli became director of strings for the next twenty-four years. After 1699 Corelli worked for the Elector of Bavaria where he taught the young violin virtuoso Pisendel. Writing almost exclusively for the violin or string ensemble. Corelli's works represent a critical link in the evolution of the baroque concerto grosso and sonata forms. Bach's instrumental style was clearly influenced by them, as was that of Corelli's other students Geminiani, Locatelli, and Handel.
