This edition features fold-out pages, which facilitate convenient page-turns. The musical text is based on Chopin's autograph manuscript.

Includes a detailed preface (in Eng./Ger.), critical commentary (German only), and the appendix includes the Impromptu Op.89 of Ignaz Moscheles for comparison (both works use similar thematic material, which might explain why Chopin chose not to publish thiswork during his lifetime).
