I know I have struggled with several this summer, and I’ve watched other cantors have trouble as well. It’s not that they are beyond our capabilities (usually!), but that we have less time in summer (no rehearsals til right before mass) to learn them well. You’ve given us other avenues to learn them (come in any time; midi file, YouTube), but for me, I think of our summer “off” as a time when we need less practice/rehearsal time, and we are doing “old favorites.”
I admitted in my reply I had ulterior motives in keeping the bar high. If I was permitted to rehearse only one piece for an upcoming Mass, it would be the psalm after the first reading. Hands down. Every week.
That said, my view is that every Catholic music director and Ordinary Time psalmist should know eight numbers: 19, 27, 34, 63, 95, 100, 103, and 145.
These are the common responsorial psalms for Ordinary Time, and settings of these psalms are appropriate any time as a replacement for the proper psalmody of the day. What do you think, you church musicians in the reading audience? Lighten up on psalmists and/or cantors?
