From a reader…
When leaving Church I noticed a deacon (not the deacon of the Mass) giving the Eucharist to the organist after the Mass had ended (up in the choir loft). There is singing or playing any time the priest or a lector is not talking. I find it hard to believe that putting music before the Eucharist in importance is allowed. Is it?
Not a lot of silence, eh?
It was common back in the day, and it is still done now, to distribute Communion to choir members or musicians who were in the choir loft during Mass.
It seems better to do this after Mass, reverently, at the Communion rail than send someone traipsing about with the ciborium, up and down stairs, and then having an awkward space in which to distribute.
There was and is a standard rite for doing this: HERE
You will note that this also describes the manner in which Communion is distributed during Mass. Indeed, in the older, traditional Missal, distribution of Communion is not described.
