This is an excerpt of a Credo from a Mass by Jacob Obrecht (1457-1505) that I found in a publication by M & R Co. Boston, MA, Mediaeval and Renaissance Choral Music, 1940. In my arrangement you'll find a simple pedal tone accompanying the two-voice canon, as well as a newly composed introduction and Amen from the text of the Credo of the Mass.
