Edited by Jarmila Gabrielova. For solo piano. Urtext Edition. Preface in Ger., Cz. and Eng. The autograph contains many cuts, overwritings and barely decipherable passages, yet it is carefully prepared and largely identical to the first edition of 1909. This first scholarly-critical edition takes all source variants into account for the first time. Includes critical commentary. Score, 53 p.
