For many centuries, the crafts of composer and performer —today steadfastly separated— were embedded in the one person. The genius of the former fuelled the virtuosity of the latter, and vice versa. This series is based on this historical circumstance, reviewing a selection of the most brilliant cases of violinist-composers of all time. From Biber and Corelli to Sarasate and Kreisler, the violin repertory composed by these performers has always cast a captivating spell over audiences, who are unable to distinguish its most intimate nuances. It has therefore been associated with supernatural forces: while Tartini attributed his sonata The Devil’s Trill Sonata to an oniric and diabolic origin, Paganini would take advantage of the rumours attributing his surprising technique to a pact with the Devil to enhance his reputation.
