First came Johann Sebastian Bach's sonatas and partitas, then Nicola Paganini's caprices. Now, with the op. 27 sonatas of EugŠne Ysa˜e, the key works in the repertoire for unaccompanied violin are available in urtext editions from Henle. Ysa˜e peppered these challenging works with extraordinary difficulties, dedicating each of them to a virtuoso violinist of his day and tailoring it to suit his special capabilities. Thanks to newly discovered source material, we are able to present a "definitive text" that in many respects supersedes the previously available text from the first edition. -the publisher
