Präludium und Fuge g-moll "Nun komm der Heiden Heiland"

A few days ago I had a strong motif in my head that wouldn't let me go. I carried it around with me while shopping, in the bathroom and ultimately in front of my Kurzweil PC-88, but it finally took more and more shape on the keyboard. To the fugue already presented, the prelude matching the chorale melody was born, which I would place stylistically somewhere between Buxtehude, Kellner and of course J.S. Bach.
I had prepared a concluding chorale, but deleted it because the monolithic movement did not fit the overall picture.
Have fun with my current composition!
