Schumann's Piano Concerto is known all over the world, yet despite its popularity it remains in a certain sense an undiscovered work. The aim with this edition is not only to provide a critical score of the work, but at the same time to indicate what questions of detail should form the focus of future research. The critical analysis offered here thus offers discussion of the relationship between the one-movement Fantasia version and the three-movement concerto version, the problem of the transition from the second to the third movement and a series of questions relating to the version completed in 1853. A booklet of facsimiles completes the volume.
