The critical edition Jean Sibelius Works (JSW) publishes for the first time all the surviving works of Jean Sibelius. The edition includes complete early versions and his own arrangements, based on a thorough study of all known sources. Some of the earlier editions are out of print, some works – even some of the central ones – have never been published, and many of the published editions are not entirely unquestionable or reliable. Thus, the aim of the present edition is to provide an overview of Sibelius’s oeuvre in its entirety, through musical texts prepared in accordance with modern editorial and text-critical principles.
A large body of Sibelius’s autograph musical manuscripts has survived. Because of the vast number of sketches and drafts for certain works, however, it would not be possible to include all the materials in the JSW volumes. Those musical manuscripts – sketches, drafts and composition fragments, as well as pages crossed out or otherwise deleted in autograph scores – which are relevant from the point of view of the edition, illustrate central features in the compositional process or open up new perspectives on the work, are included as facsimiles or appendices. This edition serves to illuminate various aspects of the works’ sources and history, as well as Sibelius’s notational practices, and is intended both for scholarly use and performance.
