For an introduction to the Lynar B3 manuscript, see here. The prelude has again no indication of a composer in the manuscript. Short as it is, it is a well written work, perhaps a very early work from Scheidemann, or one of the other Sweelinck students.
The recording was done on the sampleset, made by Voxus, of the Matthijs van Deventer-orgel in the Grote Kerk, Hijkerk.
