Arcangelo Corelli's contribution to the history of violin performance was immense. All six of his published collections of instrumental music demonstrate his exceptional skill as a violinist and composer, but it was in his Violin Sonatas, Op. 5 that Corelli had the most significant impact on violin technique. The Op. 5 collection consists of eleven sonatas and a twelfth sonata with a series of twenty-three variations on the famous "Follia" theme. All twelve pieces contain a variety of difficult violin techniques. Lina Tur Bonet is one of the most exciting violinists of the younger generation. She is accompanied by her ensemble Musica Alchemica.
