Attribution Note

In GB-Lcm 1070 (The Anne Boleyn Music Book) this piece has long been known and attributed tentatively to Compere. The attribution to Walter (along with many other pieces) in the Polish ms PL-Kj Berlin MS Mus. 40013 has not been widely noted, though the copies here and in Viadrina have previously been identified as concordances. This attribution cannot be defended in view of the date of MS 1070 (when Walter would barely have reached his late teens). On stylistic grounds (cf. In illo tempore & Planxit autem), William Kempster has argued the piece is not by Compere; he has tentatively proposed the possibility that Popule meus might be attributed to Ninot le Petit.
