The Willan Setting for Mass is one of the most common, if not the most common settings in use in Anglican Churches. There is, I think, something comforting about it (probably because of its wide usage) but it can, if used too often, become boring and thus, distracting. I’ll put it this way: I recently heard someone describe it as the mass setting every Episcopalian is born knowing. It is the Second Communion Service in the 1940 Hymnal, and is listed as Missa de Sancta Maria Magdalena in the 1982 Hymnal.
The Kyrie is number 710 in the Hymnal 1940 (and S91 in the 1982 Hymnal), the Gloria is 713 (S202), The Sanctus is 711 (S114), The Angus Dei is 712 (S158). This setting also includes sung responses to the Decalogue, 708 in the 1940 Hymnal. There is no setting for the Creed.
Below are some excerpts from this setting.
