"Arcangelo Corelli (1653-1713) was an Italian violinist and composer of baroque music. The style of execution introduced by Corelli and preserved by his pupils, such as Francesco Geminiani, Pietro Locatelli, and many others, was of vital importance for the development of violin playing. It has been said that the paths of all of the famous violinist-composers of 18th-century Italy led to Arcangelo Corelli who was their "iconic point of reference". The parts for violin very rarely proceed above D on the highest string, sometimes reaching the E in fourth position on the highest string. The story has been told and retold that Corelli refused to play a passage that extended to A in the overture to Handel's oratorio Il Trionfo del Tempo e Disinganno (premiered in Rome, 1708), and felt seriously offended when the composer (32 years his junior) played the note. 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. One can still trace back many generations of violinists from student to teacher to Corelli (the 'Corelli school'). His compositions are distinguished by a beautiful flow of melody and by a mannerly treatment of the accompanying parts, which he is justly said to have liberated from the strict rules of counterpoint." http://en.wikipedia.org/wiki/Arcangelo_Corelli
