As a disclaimer, I can be quite rigid in my progressive liberality. I was taught in the 1970's seminary, that the sung Mass should be the norm, especially on Sunday but even during the week. I don't think I ever had Mass on a Sunday where there wasn't singing of some sort.
Now that I am assisting as a "supply priest" here, there and everywhere, I have celebrated what once was called the "Low Mass" on Sundays. In the pre-Vatican II Mass or times, a Low Mass meant that the Mass itself was completely spoken, no parts sung. However, hymns could be sung at the start, Offertory, Communion and Recessional. The Propers, though, were still said by the priest, never omitted.
However, what I am experiencing is no singing whatsoever. A completely spoken Mass. People who attend it want a short Mass and don't want to sing. I see no problem in accommodating these people if there are multiple Masses on a Sunday.
However, more often than not, the Official Introit and Communion Antiphons are completely omitted. And most unfortunately, the Alleluia and verse prior to the Gospel is omitted too.
I would insist, that in a spoken Mass, the Introit, Offertory and Communion Antiphons should be spoken by the priest and the people together and a worship aid to facilitate this.
I was taught in the seminary that if the Alleluia and verse were not sung, these should not be spoken. I think that is silly. Say the dang Alleluia and verse. Not doing so is just plain dumb.
