This Kyrie by Carol E. Browning is allocated to Lent by Gather 3rd ed. I suppose a plea for mercy is especially meaningful in Lent, but a good Kyrie is for year round use.
I’ve had no luck finding this as an individual piece of sheet music at GIA, so I guess you’ll have to find it in Gather 3rd ed. collection.
For once the cantor gets only one word at a time and the assembly gets to sing everything else.
Kyrie eléison, Christe eléison, Kyrie eléison
