This is about the tenth anonymous prelude I publish from manuscript Lynar B3. It has two distinct parts or episodes (as it is one contnuous piece). In the first part the right and left hand play eighth note figurations alternatively. In the second part descending motive of eight notes in total is elaborated contrapuntally. Except for the forst entry, each entry of this motive overlaps half way with the previous entry.
