Beethoven wrote ten sonatas for violin and piano in just fifteen years (between 1797 and 1812). The way in which he set out again to find a new model for each new work is impressive. In the sonata in A major op. 47 published separately here for the first time, this genre immediately takes on a new dimension from the cadential entry of the violin, without accompaniment, and by virtuoso and concertant style maintained from start to finish. On the original title page, Beethoven had rightly noted: "scritta in un stilo molto concertante almost like a Concerto". He dedicated this sonata to the Parisian violinist Rodolphe Kreutzer, hence his nickname "Sonata à Kreutzer". Carefully developed, the urtext edition is based on the fragment of the autograph manuscript, on the original German edition, the first English edition, as well as on a copy made in the workshop of copyist W. Schlemmer and found by G editions. Henle. This copy corrected by Beethoven was used as an engraving copy for the original edition. Beethoven editor and researcher Sieghard Brandenburg also supervised the edition of the same sonata as part of the complete edition of Beethoven's works. Its preface contains important information relating to the edition of this masterpiece.
