Published in early 1806, Kreutzer's "40 Études ou Caprices" for violin are the product of his years-long employment at the Conservatoire de Paris. Their systematic and complete reappraisal of essential violin technique make them an indispensable tool of the trade for every serious student of the violin at the conservatory level. The virtuoso violinist and pedagogue Ingolf Turban acted as a consultant for this Urtext edition, furnishing modern markings to provide an ideal foundation for contemporary violin instruction.
