Is it super hard to sing the Gospel in a psalm tone and being heard without a microphone? Does this mean that before the mic was invented people back in the church could not hear the Gospel or the Priest or Deacon preaching?
Some opera singers say they are not trained to speak but only to sing. They find talking with real power hard. I guess a Priest would find singing the homily with power much easiet which it is. My vocal teacher told me he has heard people sing the homily but I did not ask when he heard it. It could have been in a Catholic or Lutheran church.

Most places aren't designed for acoustics, sad to say. Talking with power is hard.

In pre-Vatican II days, the Gospel wasn't read for the congregation hear anyhow (though it may have happened sometimes).

It might be read in vernacular at the pulpit before the sermon.

Anyway, older churches probably have better acoustics overall - no sound killing carpet, for one.

So newer churches are build with no good acustics in mind line in the older days?
People actually thought about acoustics in the old days?
Anyway, I think using psalm tones no mic is needed.

Why wasn't it read for the congregation?
Even today if a Priests say the OF alone he does not read it for a congregation.
I guess there are are resons for reading it.

Without microphones, a speaker would have to speak aloud.

Many churches nowadays have a better sound system with some sound speakers spread throughout the building.

yes but we are too much into technology instead of using the acoustics.
it has had a bad effect on us. Nowadays people sing with microphones instead of using their full potentials as singers.
I dislike micrphones other than for special occassions or for recording stuff.

Not giving the singer a microphone sounds like a great idea cuz I don't want to hear them anyway

In my opinion, it is certainly not ideal for singers to use microphones at Mass.

Is it easier to sing without a microphone? Why would that be?
I take singing lessons and never use a microphone at all. Are people who need a mic singers who do not have powerful voices?
