In this volume with the Toccatas (and Fugues) as well as individual works the Swiss organist Jean-Claude Zehnder has amply proven his mettle as a Bach specialist here. Of particular interest in this book is the Canzona in d BWV 588. Written before 1707, this early work is found in a contemporary copy by Johann Gottlieb Preller with embellishments, fingerings and a closing cadenza; this version is printed in the Appendix. Similarly, the print of the early version of the Passacaglia BWV 582 is likely to meet with great interest. Online you will find early versions, further ornamented versions, and pieces that can no longer be attributed to Bach as the Kleines harmonisches Labyrinth BWV 591 and the Prelude in G BWV 568.
