The service of Holy Communion at the later service is a sung service (except in the summer months, mid-June through the Sunday of Labour Day). We use one of two different musical settings of the mass: Merbecke, and the Schubert Deutsche Messe.
John Merbecke (c.1505-c.1585) based his setting on traditional Latin plainsong and adapted it to the English texts of the then new Prayer Book. It was published in 1550. The organ accompaniment used at Saint Mary’s was arranged by Healey Willan (1880-1968).
Franz Schubert (1797-1828) wrote five settings of the mass. His Mass in F major, D872 (Deutsche Messe, German Mass) was written in 1826. The edition used at Saint Mary’s is a 1985 adaptation to ICET (English) texts by Richard Proulx. In his foreword to the edition, Proulx describes it as “essentially congregational music, [. . .] participatory music of the finest kind. Although technically easy, this music is unmistakably Schubert’s (mature music composed just two years before his death) and displays the melodic grace we associate with his [. . .] songs.”
