The organbook of Matthias Rottenau (Mus. Ms. 40615 from the Staatsbibliothek zu Berlin) contains numerous works from unnamed composers. All the works contained are sorted by category. First come all the preludes (Preambuli), than Introiti, Toccate, Canzoni, Capricci and finally the Ricercari. The first bunch of pieces in each section is preceded by a nicely drawn Initial, giving the title of the piece, the tonus and (though not always) the composer. The last bunch of pieces in each section go without initial, though space is left open where one could be drawn in. So it’s only a supposition that the pieces without initial that follow for example, the Ricercari with initial, are Ricercari as well.
Today’s score is again one of those supposedly Ricercari. It’s actually without title, without tonus and without composer. but for now I designate it as a Ricercar, octavi toni. If someone knows for certain that’s correct or not, I’d like to hear it. It is a well written three voice piece. It is a monothematic piece, so it could equally well be called a fugue.
The recording was done on the sample set of the Bader-organ in the Walburgiskerk in Zutphen by Sonus Paradisi for Hauptwerk.
