The Saint Paul’s Choir of Men and Boys sing Palestrina’s glorious and beloved music, composed around 1562, within a contemporary Mass for the feast day of Saints Cyril and Methodius. In the lecture and discussion preceding the Mass, Prof. John Baldovin, S.J. and James Kennerley, FRCO, examine the evolution of the Eucharistic worship before the Council of Trent (1545-63), the Council’s teachings on the Eucharist and its debates on the role of music in liturgy, the musical characteristics of Palestrina’s groundbreaking composition, and the way to integrate this music into contemporary Catholic worship.
