Prelude and Fugue in E Minor Uploaded by: Agnus_Dei Composer: Walmisley, Thomas Attwood Organ: Hereford Cathedral Willis Organ Software: Hauptwerk IV Views: 231
Here's my take on this well-known work. The edition I'm playing from is "A Bach Organ Book for Students" edited by C. H. Trevor and published by Elkin.
I am cheating a bit by using pistons. The registration changes in the fugue would be impossible to pull off on the real instrument without 2 assistants.
