In certain respects, this edition complements the volume of Keyboard Works of Doubtful Authenticity (BA 5250). It contains works which have survived bearing Johann Sebastian BachÂ's name or were later attributed to Bach, but where Bach has been ruled out as composer in the opinion of the editors on stylistic grounds or following a critical examination of the sources. But having said that, it is hard to be negative about these compositions which are of a consistently high quality. Furthermore this is largely unknown repertoire; almost half of the pieces in the volume are previously unpublished. As a result, this edition invites curious and open-minded musicians on a voyage of discovery.
