This performing  Urtext  edition contains “free” organ pieces (i.e. not based on a chorale) and  chorale partitas from various source traditions. Owing to doubts about their authenticity , they did not appear in the New Bach Edition until the end of 2003 (NBA IV/11).  Today, however, scholars view Bach’s authorship of these pieces either  as certain  (e.g. the valuable Fantasy in C minor, BWV 1121) or at least worthy of serious  consideration.<br>
<br>
We therefore decided to issue them in this separate performance edition.<br>
