Chopin left behind only a few works in the main form of the classical era, the sonata – of these, the Piano Sonata op. 58 certainly numbers among his most important. Formally, it is more conventionally structured than the earlier b minor Sonata, but just like its sibling work, it is full of romantic poetry, irresistible melodic inspirations and brilliant virtuosity. The revision of the previous Henle Urtext edition has now been based on a broader foundation of sources: alongside a further student copy which contains revealing corrections from Chopin’s lessons, a later impression of the French first edition is of particular importance, since Chopin’s corrections are implemented here. Consequently, the b minor Sonata is now available with an improved musical text and extensive commentary texts!
