I recently wrote this trio prelude for organ over the tune of a hymn by Johann Schop, which he wrote in 1641: https://youtu.be/bVW0ja4hj8Q
The lyrics of "Sollt ich meinem Gott nicht singen" were written by Paul Gerhardt in 1653. The hymn can be found under no. 325 in the German Evangelisches Gesangbuch (EG).

It's true that the trio may seem to sound quite modern in its whole chromaticism, but when writing it, I was actually influenced by some of J.S. Bach's choral preludes from the Little Organ Book (Orgelbüchlein, bwv 599 - bwv 644), as some of them contain the cantus firmus in canonic form (bwv 600, 608 [,613], 629...) - furthermore, I was influenced by one of my favourites from that collection: bwv 617 ("Herr Gott, nun schleuß den Himmel auf", which means ~ "Lord, God, unlock Heaven, now"), and by bwv 906 for harpsichord (which is very chromatic and, maybe, quite "futuristic" for Bach's time...), especially the (regrettably unfinished) fugue.
