BA5243
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. 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.
