O Herre Gott, begnade mich

The fourth anonymous piece of which I have copies of the original manuscript is a magnificent piece on the melody of "O Herre Gott, begnade mich". The text is based on Psalm 51, the melody is not, at least not on the melody Psalm 51 has in the Genevian Psalter.

The melody is rather long and so is this composition. The melody is in the so called Bar-form: A-A-B. In this composition the first A is written for the soprano voice, richly embellished. The second A is played by the pedals, in long notes. The B is again in the soprano voice, though not as richly embellished as in the first A.
Another noteworthy characteristic of this composition is that in the middle of the B-segment the meter changes to 6/4.for eleven bars, after which it return to the opening 4/4.
Probably an expression of the text, though I could not determine which words were the inspiration for this change in meter.

Again a piece that shows that enormous treasures are still hidden in manuscripts, just because editors want to put a name on a composition and ignore anything that is anonymous.
Yes, I know, there are exceptions. This composition however is not published as far as I could find.
So I am glad I have consent of the owning library to publish these pieces. First I want to finish transcribing the fifth piece (by far the longest), then I'll publish all five of them.
