A wide, and often conflicting, variety of analyses has been published about the piece: for instance, in literature on organ music, it is often described as some sort of program music depicting a storm, while in the context of Disney's "Fantasia", it was promoted as absolute music, nothing like program music depicting a storm. In the last quarter of the 20th century, scholars such as Peter Williams and Rolf-Dietrich Claus published their studies on the piece and argued against its authenticity. Bach scholars like Christoph Wolff defended the attribution to Bach. Other commentators ignored the doubts over its authenticity, or considered the attribution issue undecided. No edition of the "Bach-Werke-Verzeichnis" listed the Toccata and Fugue among the composer's doubtful works, nor does its entry on the website of the Bach Archiv Leipzig even mention alternative views on the attribution issue.
