The surviving autograph of Franz Liszt's b-minor Sonata is a fascinating document that illuminates the compositional process: many cuts and paste-overs show how Liszt refined the architecture of the work. The previously available facsimile of the autograph in the Henle catalogue also allowed a profound look into this work process - but it was not possible to see what Liszt had originally notated in the passages that were pasted over. These paste-overs have since been removed and in this new edition we can see for the first time what is hidden behind them. The knowledgeable introduction by the Liszt expert Mária Eckhardt provides an abundance of information and a unique look over the composer's shoulder.
