Liszt reserved his attention to the Weber’s Konzertstück during all his life: he played it, he teached it and he edited it. The autograph discussed in this article presents the six pages of drafts (never published) composed by Liszt for the edition of Konzertstück to be inserted in the Instructive Ausgabe klassischer Klavierwerke, a collection of piano’s work directed by Sigmund Lebert and published by Cotta.
The autograph is kept in the collection of manuscripts of Istituto Liszt (Bologna). It permits to extend the investigation on the relation between Liszt-Weber from the memories of Liszt’s interpretation of the work and his reduction for piano solo to a comparison among the drafts, the original version of Konzertstück by Weber and the edition for piano solo.
