||The choice of cantus firmus for this Mass, a plainchant sung on the feasts of only two saints in the Sarum calendar, Margaret and Winifred, suggests that Ludford may have written it for St Margaretís church, Westminster, his own parish church in which he was married, served as a guild member and churchwarden, and was buried. Perhaps it was one of the compositions in the book of music which St Margaretís bought from him in 1533/4. Whatever the case, it is arguably his most Ďmoderní Mass: succinct and lyrical, with an imaginative handling of texture and many telling harmonic touches. [Pending a reprint, please note that the breve D in the Tenor in Credo bar 120 (page 19) should be a semibreve D followed by a semibreve rest, and that the first note in the Treble in Sanctus bar 176 (page 33) should be B, not high G.] For five voices: SATBarB. viii + 40 pages.
