Some people who attend funerals may not be familiar with either the movement in a Catholic funeral, or even a Mass. Guide them, the rite suggests:
40. The presiding minister or an assisting minister may quietly direct the assembly in the movements, gestures, and posture appropriate to the particular ritual moment or action.
An important operating principle here is “quietly.”
41. Processions, especially when accompanied with music and singing, can strengthen the bond of communion in the assembly. For processions, ministers of music should give preference to settings of psalms and songs that are responsorial or litanic in style and that allow the people to respond to the verses with an invariable refrain. During the various processions, it is preferable that the pallbearers carry the coffin as a sign of reverence and respect for the deceased.
These days, few parishes have their own cemeteries, and processions are usually conducted by motor vehicle.
