Catalogue

This list includes all Beethoven’s works with opus numbers and without opus numbers: WoO, Hess, Biamonti or uncatalogued. Opus and WoO (“Werk ohne Opuszahl”) numbers are taken from Georg Kinsky and Hans Halm, Das Werk Beethovens: Thematisch-bibliographisches Verzeichnis (Munich: Henle, 1955). Hess numbers refer to works not contained in the old complete edition; they are listed in Willy Hess, Verzeichnis der nicht in der Gesamtausgabe veroffentlichten Werke Ludwig van Beethovens (Wiesbaden: Breitkopf & Hartel, 1957). Also see The New Hess Catalog of Beethoven’s Works, edited, updated, and translated with a new foreword by James F. Green (West Newbury, Vt.: Vance, 2003). There is no fully comprehensive catalogue of Beethoven’s numerous unfinished or fragmentary works, although an attempt was made in a little-known thematic catalogue compiled by Giovanni Biamonti by 1968. See in this regard the Web site www.unheardbeethoven.org.
