I’m only in charge of the music for Easter Sunday, so this doesn’t pertain to me.
But at my old parish, where I played the piano, the choir director always had us sing a capella on Good Friday. It was the only day of the year when I got to sing instead of play.
Honestly, I just thought it was something she had decided to do on her own. I had no idea it was in the GIRM.
Thanks for pointing this out. I’ll bring it up with the priest in charge of liturgy after Easter – maybe in the summer.
Incidentally, at the mass where I choose the music, I’ve hardly played the organ at all throughout lent. Last Sunday I turned off the organ after the Gospel acclamation. Our congregation has no problem singing without it, and we can hear them (even from the choir loft) when the organ is off.
God bless everyone’s Triduum and Easter!!
