The Bayerische Staatsbibliothek provides digital copies of two collections of chorale preludes by Friedrich Wilhelm Marpurg. The first contains 21 compositions. The second one is sadly incomplete and contains only 5 complete compositions. This fugue on the melody of "Allein Gott in der Höh" is one of them.
Thought the title states it is a fugue on "Allein Gott in der Höh sei Ehr" the choral melody is actually not very recognizable in this fugue. Or perhaps better: not at all recognizable. Nevertheless, it is a nice fugue to play, albeit not a very good one.
The recording was done with the Hauptwerk software and the sampleset, made by Sonus Paradisi, of the Schnittger organ in the St. Martini-kerk, Groningen (https://www.sonusparadisi.cz/en/organs/netherlands/groningen-st-martini.html).
