I agree that Joy exists, however, it is not to be garnered from the social hysteria found in some of the modern “concert” churches so popular in a sadly slow to thought culture. Expressions of fervor are, as many wise posts have stated, cultural in nature and thus clapping may well be a valued component of worship in Africa or Hispanic culture for example. I am just old fashioned enough to find the happy clappers distasteful. Horses for courses, I guess.
Social hysteria? Where do you go to church?
That’s funny. I’ve never been to a Mass where there was anything of the sort.
OP: Here’s the bottom line.
In our culture, people don’t show emotion. Period. Seldom. Certainly not at Mass unless it’s to glare at some woman with a crying baby.

If your congregation bursts into clapping to the music at the Recessional, and the priest happily does too, it’s fine.
If he looks like’s about to blow a gasket, I’d say “no, it’s not ok”.
Read the cues from your pastor. I’ve never known a priest who was slow to voice an opinion on this. I say this because inasmuch as people on CAF believe that they can make all the liturgy decisions in the parish without the benefit of being asked to view said opinions, the bottom line is that it is the pastor’s call. If it bugs you, go ask him what he thinks about it. If he’s upset, he might be glad to know that some in the parish feel as he does and he might be moved to say something. Or, he could tell you that it’s not liturgical abuse to clap to a lively hymn of praise.
Either way, you get a genuine answer from someone who can make the call.
peace.
