The last piece from manuscript Mus.ms. 30190 is a prelude on “O Welt, sie hier dein Leben”. It’s a four voice piece, with the cantus firmus in the alto voice. It’s bit difficult to hear, but it’s defenitely there. And this is the last piece by Oley for now. Perhaps in future I’ll find another manuscript source for more pieces by his hand, but at the moment I have no more.
