Manuscript Mus Ms 30195 contains three preludes by Johann Peter Kellner, two of which are followed by a fugue. As far as I could find these three have not been published before. They are typical works by Kellner in that the quality is not very consistent. The first has a very uninspired prelude that is followed by a very nice fugue. The second has a nice idea that is however unevenly worked out and contains a lot of compositional or transcription errors. The third and last one is the most consistent, with a concertant prelude and a short manualiter fugue, based on a chromatic theme.
This is the first of the three. The manuscript has two alternatives for the solo pedal line. Both are represented in the score, in my performance I chose the alternative in the footnote.
The recording was done with the sample set of the Eisenbach organ of the St. Bartholomäus church in Friesach, by Piotr Grabowski
