Se considerarmos que a duração de uma eucaristia dominical andará à volta de uma hora, estamos a falar de um acréscimo de tempo na ordem dos 2%.
A conclusão é que o contributo do canto dos diálogos litúrgicos entre o celebrante e a assembleia para a duração total da celebração litúrgica da eucaristia é mínimo.
Não parece razoável, portanto, invocar razões de tempo para não cantar os referidos diálogos.
[T]here are always those persistent myths surrounding things liturgical, and the practice of singing the dialogues at Mass is certainly no exception.
It does take time to sing those dialogues...but it also takes time to speak them. And you do have to either speak them or sing them... it's not as though they are omitted if they aren't sung. So how much extra time does it take to sing the dialogues as we are encouraged to do rather than speak them?
There's an easy way to find out.
I recorded the dialogues (from the new translation) that would ordinarily be sung at Mass:
Introduction to Mass
Our Father with Introduction
Deliver Us Lord…
For The Kingdom…
I recorded them spoken, and then the same texts sung using the notation indicated in the new missal translation.
And so how much longer would Mass take if you sung ALL of these dialogues? I asked a few people this past weekend, including two Priests, and got quite a range of responses. One person guessed that it would probably add about 10 minutes to Mass. One of the Priests guessed that it would only add about 7 or 8 minutes to Mass. Another said that it would only add about 5 minutes or so to Mass...
But when you actually compare the time that it takes to speak and sing the same texts, we get a very different answer.
In reality, it would only add about 1:18 - a minute and eighteen seconds - onto the Mass time! And that would be if we sang ALL of the dialogues... and the Lord's Prayer! That's less time than it takes to make a few announcements, or thank a couple of servers at the end of Mass. And in realistic terms, we're talking about the difference between ending Mass at 11:58 or ending Mass at 11:59. That doesn't exactly seem like an unreasonable extension of the Mass time given the importance that has been attached to the practice of singing the dialogues.
So when the issue of singing the dialogues comes up as you begin preparations for the new translation, and the inevitable voice is raised in objection - "that takes way too much time during Mass", you can point out that it takes probably 3 times longer to sing the closing hymn... and so perhaps we should discuss cutting that out first.
