Peace be with you!
I’ve never been to a TLM yet either, but I have been to an NO Latin High Mass and a Dominican Rite Low Mass. The Dominican Rite Mass was, I’m guessing, nearly identical to the TLM. The only noticable difference (and I was only going off of what I knew of the TLM from reading about it and talking to people) was that in the confeteor “mea culpa” was said once instead of “mea culpa, mea culpa, mea maxima culpa”. The priest faced the tabernacle, though they just set the candles on the opposite side of the altar (they didn’t take out the altar and use the old one with the tabernacle on it). There was a lot more kneeling and there were different prayers said too. It wasn’t too hard to follow in the missal, though, so I wouldn’t expect you will have trouble. After the Mass was over we said the “Hail, Holy Queen” and St. Michael prayer (kneeling, with the priest and acolyte kneeling in front of the altar). I’ve only been to this Dominican Rite Mass once, but that church is a Dominican parish and they do the Mass on the first Saturday of every month, in the morning. I’m going to try to go as often as I can (this same church does a Gregorian chant Mass every week, part in Latin, and Latin High Masses on some feastdays).
Anyway, you’ll have to let us all know how it goes!
In Christ,
