Georg Andreas Sorge, Helft mir Gottes Güte preisen | Secrets of Organ Playing Contest, Week 106

This is my entry for the Secrets of Organ Playing Contest, Week 106. I play Sorge's choral prelude on the melody of "Helf mir Gottes Güte preisen".

Georg Andreas Sorge (1703 – 1778) was a German organist, composer, and, most notably, theorist. Sorge’s first professional appointment was at the age of 19 as court and town organist at Lobenstein, a position that he maintained until his death. Though Sorge is mostly remembered as theorist, he was also a prolific composer. His 12 Trios for organ are still used in organ playing education.

That Sorge had a knack for writing trios is also clear from his choral preludes. His best choral preludes are the ones that were conceived as choral trios. Typically Sorge writes a three part introduction and accompanies the choral melody with a two part accompaniment.

Sorge's choral prelude on the melody of "Helft mir Gottes Güte preisen" is a very nice example of this type of choral prelude. Sorge writes a very lively introduction in three parts and accompanies the choral melody with a two part accompaniment employing the same motives as the introduction.

Sadly, Sorge just finishes the piece where the chorale melody ends. I would have expected Sorge to repeat the introduction. As I like the introduction a lot, I decided to add it at the end of the piece. I think it creates a nice musical structure, though I had to add half a bar to create a firm ending in g minor.

Of course it's very debatable to adjust someone else's composition in this manner. I think it creates a satifying whole. What do you think?
