Of the Lynar manuscripts in the B series, manuscript B9 is the shortest. It contains only two organ preludes. The are both without indication of a composer. The first of them is unique in the collection in that is has a five part texture. Though it is without the indication "pedaliter" it seems certain that it is to be played with the pedeals. Hence I created a score with three staves.
