Following up on one way to begin a wedding Mass, form 1, there is a second option, a simpler one:
48. At the appointed time, the Priest, wearing an alb and a stole and chasuble of the color of the Mass to be celebrated, goes with the servers to the place prepared for the couple or to his chair.
Some variation of this is the more common practice, at least as I’ve seen it in the US. It presumes the entrance of the couple in some manner in keeping with family, ethnic, or cultural tradition:
49. When the couple have arrived at their place, the Priest receives them and warmly greets them, showing that the Church shares in their joy.
I continue to tell couples I assist in preparing for their wedding liturgy that the Church has no preference as to how they enter. It can be formal with the ministers, as in OCM 45-46, or however they wish, according to paragraph 49.
The second form does foresee a song:
50. Then, during the Entrance Chant, the Priest approaches the altar, reverences it with a profound bow, and venerates it with a kiss. After this, he goes to the chair.
How would this translate into music? I imagine a “traditional” instrumental for the entrance of the wedding party, and a song sung by all present after the couple is in place.
