The Sonata in B minor op. 58 (1844) is Chopin's third and most important contribution to this genre. By fundamentally reassessing the sources, the editors have arrived at a revised reading of the work. It is based on the version of the French first edition, in which Chopin made changes right up to the printing stage and beyond, and which is presented here for the first time in an Urtext edition. Some of the most important variants are found in the first movement (e.g. in m. 96), but also in the Largo and the Finale.

A Foreword (Ger/Eng) provides information on the genesis and the complicated source filiation. This new edition is rounded off by notes on performance practice by Paul Badura-Skoda, a pioneer of historically informed playing, and Hardy Rittner, Professor of Piano at the Hochschule für Musik Freiburg and author of a current fundamental work on Chopin's piano playing published by Bärenreiter (BVK04005). Questions of tempo, ornamentation, use of pedal, rubato, cantilena and hidden inner melodic lines are addressed. The original Chopin fingering has been supplemented by the fingering of Paul Badura-Skoda and Hardy Rittner.
