The Lynar manuscripts were preserved in the holdings of the Duke of Lynar in Lübbenau, and are therefore also known as the Lübbenauer Orgeltabulaturen. The seventh manuscript in the B-series contains 5 anonymous choral preludes/variations to Psalms and one to the choral "Erhalt uns Herr".
The fourth of the compositions from this manuscript is a set of variations on the melody of Psalm 100. There are four variations, set up as two continuos pieces, with two variations each. The first piece has two variations with the melody in the soprano voice. The second one has two variations with the melody in the tenor voice.
