This publication includes organ and keyboard works by composers from Bach’s time. For the first time, the original version of Bach’s famous Toccata in F major is published in an edition based on the sole source, manuscript Bach P 803 in the Berlin State Library.

The collection also includes a partita by Friedrich Erhard Niedt and a sonata by Johann Adolph Scheibe , published for the first time in a modern edition. This makes the edition the first to give an overview of keyboard music of Bach’s time primarily without pedals, a repertoire of which only a few pieces survive. The critical edition is based closely on surviving sources and includes a Critical Commentary, List of Sources, numerous facsimiles and an extensive foreword with chapters on the techniques used in preparing the edition and performance practice.
