Edited from ms Segovia cathedral, with critical comment; no tekst survives with this piece, based upon melody of Hayne van Gizeghem. For identification of Roelkin as Rudolf Aricola see and critical note of this piece.
This piece could be vocal, if Van Gizeghem's melody was sufficiently well known that people would automatically know what words to sing. However, the added voice has a 2 1/2 octave range, which could well indicate an instrumental setting. Tagged for both.
