Extended Choir Challenge

My only previous experience as an extended choir member was singing Haydn’s Creation with the Cape Cod Symphony several years ago. This year I was invited to join the choir for a recording of Miserere Mei, Deus (Psalm 51) by Josquin de Pres (French composer 500 years ago). This piece is a five-voice version of the psalm we chant every Friday at Lauds, so the Latin words are very familiar. For the recording the challenge is to sing together, in time, in tune, with the same tone, while reflecting the full meaning of the words. Only by the grace of God, much help, and a great deal of work can I hope to reach this goal. The photo shows the score open to the most difficult bass line I am to sing. I now have a much richer understanding of what it means to sing to the Glory of God!
