EVIN ALLEN was commissioned by Sacred Music Symposium 2025 to compose a polyphonic ‘middle section’ for the GLORIA from Mass III, often denoted by its trope name: Missa Kyrie Deus sempiterne. This year, I’m traveling from Singapore to serve on the symposium faculty. I will be conducting Palestrina’s ‘Ave Maria’ as well as teaching plainsong to the men. A few days ago, I was asked to record rehearsal videos for this beautiful polyphonic extension. (See below.) This polyphonic composition fits ‘inside’ GLORIA III. That is, the congregation sings for the beginning and end, but the choir alone adds polyphony to the middle. The easiest way to understand how everything fits together is by examining this congregational insert.
