BA5266
The present volume is an updated edition of Series IV, Volume 6 of the "New Bach Edition" (NBA), prepared by Dietrich Kilian in 1964. The discovery of new sources and a reassessment of existing handwritten copies have brought about changes to the contents of the volume, which now includes the "Fantasia in C minor" (BWV 1121), the "Fantasia in G major" (BWV 571), the "Fugue in G major" (BWV 577) and the C major version of the "Toccata and Fugue in E major" (BWV 566). On the other hand, the "Prelude in G major" (BWV 568) as well as the alternative versions of the "Fugue in C minor" (BWV 574a) and the "Prelude in A major" (BWV 536a) have been discarded as presumably spurious.
